Catalyst vs one without catalyst What is different?

The term catalyst is much more general than the term hardener, since hardening is only one of endless numbers of processes which can be catalysed. A hardener, therefore, would be a specific type of catalyst.

one name for a catalyst is... to be onis i have no idea myself xxx

By definition a catalyst cannot affect equilibrium because although a catalyst can speed up a chemical reaction, it cannot change the thermodynamics of it, and equilibrium is determined solely by thermodynamics. A catalyst may help a system reach equilibrium more quickly, but it will not change it. One possible way a catalyst could affect equilibrium is by introducing a catalyst that affects a different reaction involving the substrate or products of the original reaction, but…

A catalyst is a character tha brings about change in the story. For example, a catalyst's actions could cause one character to lose trust in another, or something of the sorts. Basically, if the story takes a different course because of a certain character, that character would be a catalyst.

A catalyst is something which speeds up a chemical reaction without itself being one of the reactants or products (in other words, without being consumed). Magnesium sulfate is probably a good catalyst for some reactions, not for others. What reaction are you interested in? Best, Prof. Topper ========================================================== A catalyst is a substance that accelerates a chemical reaction without being changed by the reaction. Different substances catalyze different reactions. For example, platinum catalyzes the burning…

The correct answer is a simple one: The system is unaffected by a catalyst in a system in equilibrium.

Cracking , Cracking is the name given to breaking up large hydrocarbon molecules into smaller and more useful bits. This is achieved by using high pressures and temperatures without a catalyst, or lower temperatures and pressures in the presence of a catalyst.

A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added

There are 2. One before the catalyst up front and one behind the catalyst.

An enzyme: the biological catalyst. May be made of one or more proteins joined together.

A catalyst accelerates the process of a chemical reaction. If a reaction is a slow one then by introducing a catalyst would speeden up the process. For example :- The reaction between hydrogen and nitrogen to create ammonia is a slow reaction. Finely divided iron act as a catalyst.

There are different catalysts, it depends on the chemical reaction. There is no one powder called catalyst.

Add a catalyst. Added: Temperature Pressure, concentration, dispersion degree Catalyst, enzyme

Most of the metals in the periodic table are used as catalyst for one reaction or the other

catalyst is one

Iron is one of the magnetic metal. It is used as a catalyst in Haber process to produce ammonia N2 + 3H2 ----------- 2NH3

Organic catalysts (which sometimes mean "enzymes"), are usually proteins. One example of an organic catalyst that is NOT a protein is ribozyme.

heterogeneous and homogeneous are words used to describe a system, not a single element. For example, with regards to catalysis you could have a homogeneous catalyst which means one that works in the same phase as the reactant (i.e. both solid or both liquid or both gas) or a heterogeneous catalyst, which works in a different phase to the reactant, so a solid catalyst for a gaseous reactant etc.

CARULITE® catalyst is a chemical catalyst made from a combination of oxides . The brand CARULITE® catalyst is owned by Carus Corporation. One use is in air purifying equipment to convert CO (carbon monoxide) into CO2 (carbon dioxide).

A catalyst works by providing a reaction route with a lower activation energy. An inhibitor slows a reaction and can work in several ways, for instance by tying up one of the reactants. We also use the term when we say catalyst inhibitor, which is something which binds to the active sites on a heterogeneous catalyst.

Replace it with a new one.

no one knows

NO, it's one part of a glue.

Because it lowers the activation energy of a reaction and allows the reaction to occur faster. An enzyme is a biological catalyst instead of a synthetic one.

There are plenty of places in order for one to purchase a Cisco Catalyst 6509 Switch. However, it is strongly suggested that one should order from the website eBay.

Enzyme slow down a reaction while catalyst speed up reactions. Enzyme contain a zinc content which makes it a metal, as well as catalyst; so that is one example of their simularities.

The ATI catalyst control center is a product manufactured by AMD. One can contact AMD by calling their corporate offices in Sunnyvale, Austin, and Canada.

Iron is one example of a catalyst, used in ammonia synthesis. Nitrogen oxide and platinum are another example, used in sulfuric acid manufacturing.

One of the most common examples of a catalyst is manganese dioxide, which is commonly used for combustion or fro turning hydrogen peroxide into water and oxygen

No one knows yet.

I am sure there are other types of mercury related catalysts in terms of chemistry, but one that stands out is mercury-aluminum amalgum, which is used as a reductive catalyst in organic chemistry.

There are 4 all-together. They are located on the exhaust one in front of the catalyst & one behind the catalyst. This apply's to the driver side & passenger side.

A catalyst changes the rate of a chemical reaction by temporarily interacting chemically or physically with at least one of the reactants or with one of the activated intermediates formed by the reactants as part of the reaction to change the activation energy required for the reaction, but always in such a manner that the catalyst is "regenerated" in unchanged chemical form by the end of the overall reaction.

Catalysts don't get used up, we can use one forever without it getting used up. So they save a lot of money.

There is no sensor three on this car. Sensor one is pre catalyst, sensor two is post catalyst.

Handling the local Viet Cong (VC) in South Vietnam was one thing. When northern troops began infiltrating down into the South, that was another. That may have been the "catalyst."

That truck has 4 o2 sensors, there are two catalyst converters on this truck as well. Bank one (Driver side), bank 2 (passenger side), sensor one is before the catalyst converter , sensor 2 after. There are two catalyst converters on this truck as well. Follow the exhaust system back from the engine and you will find them. A scan will tell you which one you are looking for.

Only small quantity is need for a reaction They are specific. One catalyst is need for specific reaction only Physical properties may change during a reaction but no it does not take part in the reaction.

Well Platinum is an element so there is really only one type. However, platinum may be used as "sheet" or finely powdered if it was going to be used as a catalyst. Alternatively, it may be used to "plate" a less expensive metal to also act as a catalyst for example in a catalytic converter.

An oxidizing agent is something that removes one or more electrons from something itself (the oxidizing agent itself gains one or more electrons). A reducing agent is something that gives electrons to something else (the reducing agent itself looses electrons). A catalyst is something that speeds up a reaction although the catalyst is not consumed itself in the reaction. The catalyst does this by lowering the activation energy of the reaction. See the Related Questions…

If that is the only code you are getting and the car has high mileage (90k +), the odds are in favor or the front pre-catalyst needing replacement. That car has 2 pre-catalyst converters, one for each bank, that run from the exhaust manifold towards the catalyst itself. The first one (also called front bank, left bank or bank 2) is the closest to the radiator. The second one (also called rear bank, right bank…

This is a catalyst. A catalyst doesn't get destroyed during the reaction. Rather it's more of a reaction site where two substances can combine. One example of a catalyst is amyl alcohol, which can be used to produce pure potassium metal. However, it's destroyed during the process if there are impurities in the reaction because it's consumed in other reactions. Other examples of catalysts include catalase, platinum, and manganese(IV) oxide.

HR catalyst are the group of Human resource professions with one aim and provide solutions for the business's are well equipped with the HR policies of an organization and ensure the same from the employees as they are organization's vital resource.

A catalyst speeds up a reaction, by lowering the activation energy of the reaction. This may be one reason with an explanation, However I think they may count as separate reasons.

As far as I'm aware, the work "catalyst" only applies to things which work on enzymes. Baking powder is a mixture of an acid and an alkali, which reacts upon adding a liquid by releasing Co2. (Although some also react upon heating). It is a chemical reaction, not an enzymatic one, therefore I don't think you can consider it to be a catalyst.

One property of transition metals is that all elements and compounds in transition metals act as a catalyst ( speeds up chemical reactions. ) xcool77

Yes enzymes are proteins that can lower the energy of the transition state in a reaction which is what a catalyst does. One of the first enzymes to be characterized is called Catalase for it's function as a catalyst in the breakdown of H2O2 into O2 and H2O.

If your question is "What affects catalyst performance?" (i.e. what stops them from working) then there are 2 main things: Atoms permanently bonded to the surface, blocking it, and so that stops other reactant molecules from sticking to it (catalyst poisoning) Catalyst sintering: This can be seen on high temperature solid metal catalysts, where there is a gradual loss of surface area for reactant molecules to stick to as a result of the individual catalyst…

Catalysts can be used for very different purposes, because they all work at different temperatures. If a company wanted to produce a product by reacting chemicals at 500 degrees Celsius, then they would have to buy a catalyst that worked at that temperature. However, they wouldn't buy any old catalyst, they would look for the cheapest one available that works at the temperature they need it to, so they can save a bit of money.

Normally, they're made of some kind of ceramic material substrate covered by a thin layer of a metallic catalyst. At one time, the catalyst was at least partially platinum; I'm not sure if that's still true or not.
