Catalysts and Catalysis

A catalyst affects a reaction by speeding it up. A catalyst, remember, does not participate as a reactant or product in the reaction. It facilitates the reaction by lowering its activation energy, making the reaction easier to happen.

Not all catalysts are metallic. Catalysts can be made from a variety of materials, including metals, metal oxides, zeolites, and enzymes. The effectiveness of a catalyst depends on its specific chemical composition and structure.

It speeds up the reaction that produces ammonia.

no, because enzymes are specific which they only catalyze one type of reactions.

enzymes are protein molecules that act as biological catalysts

HCl only has one acidic proton. K2CO3 can accept 2. so twice as amny acid molecules are needed to neutralise the base.

All enzymes work best at a certain temperature and pH. They also need a substrate to work on. A change in pH or temperature will inactive it by denaturing it. If the substrate is very low in quantity or is absent, the enzyme will be inactive.

A character who makes events happen.

I searched for this mechanism for along time & I finally found it at this site:

at this site under the category of:
synthesis of aspirin
the file that will be downloaded contains the mechanism

hope I could helped you...

One of the compound of Pt that is used as an anti cancer drug is cis platin ie; Pt(NH3)2Cl2. In this compound the two NH3 groups are on same side by which they can link to the nitrogen bases in the DNA of the malignant cell and can prevent their proliferation.

Prices on both commodities depend on the market for which they are most closely associated with as well as the time of year ("season"). A gallon (Methane converted from MMBTu unit of measure to Gallon) to gallon comparison of Methane ("Natural Gas") to Propane currently tracks close, in some markets, Methane yeilding just under a dollar & propane above a dollar. (Note: prices are always subject to market conditions; supply, demand, associated expenses to take the product to market.)

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.

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

The terms reactant and reagent are often used interchangeably-however, a reactant is more specifically a substance consumed in the course of a chemical reaction. Solvents, though involved in the reaction, are usually not called reactants. Similarly, catalysts are not consumed by the reaction, so they are not reactants. In biochemistry, especially in connection with enzyme-catalyzed reactions, the reactants are commonly called substrates. So, it will be literally wrong to call catalyst a reagent.

Catalyst ensures that the activation energy of the molecules is lowered so there is effective collisions,and it does this in two ways;the transition and absorbtion states but inibitors even raises the activation energy and causes in effective collisions.

These molecules are called substrates.

Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.

its an iron catalyst (iron oxide)

temperature,pH and substrate concentration

A substance that lowers the energy needed to start a chemical reaction is a catalyst.

There is more than one method for naming enzymes (which can be confusing when it comes to classification). However, the most common method is by using a prefix that represents the substance or substrate upon which they act or affect, followed by the suffix "ase" (which just labels the substance an enzyme). For example: The enzyme protease is the catalyst for converting proteins into their component amino acids.

In Biology, enzymes are proteins that act as catalysts in the body.

A reaction can be sped up by increasing the temperature, which provides more kinetic energy for the molecules to react. Additionally, increasing the concentration of reactants allows for more collisions to occur, speeding up the reaction. Increasing the surface area of the reactants can also help by providing more contact points for the reaction to take place.

Yes, enzymes are proteins that catalyze biochemical reactions in living organisms. They facilitate the conversion of substrates into products by lowering the activation energy required for the reaction to occur. Enzymes are essential for various metabolic processes and are highly specific in their actions.
