Chemical manufacturers use catalysts because they speed up the rate of the reaction taking place, without effecting the chemical formation of both the reactants (which form the product) or the catalyst itself.

If a maximum reation rate rate is 350 molecules product minute list 2 things that can increase the product rate?
In general, chemical reaction rates can be increased by the use of catalysts, and often by increasing the temperature.
What is the use of catalysts?
A catalyst helps speed up a chemical reaction. For example, a catalyst of acidified dichromate ions or acidified permanganate ions can help speed up the reactions of oxidation of an (alcohol into an aldehyde?) etc. Catalysts are used for reactions which would usually be of a very slow speed.
Why are transition metal are majorly use as catalyst?
Yes, transition metals used as catalysts. They make good catalysts because they can easily gain and lose electrons unlike the other elements.
Do catalysts speed up a chemical reaction or slow it down?
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.
Is ATP a catalyst?
No, they simply provide the energy for the reaction to occur. Specific enzymes are the catalysts, as they are the ones to lower the Ea of the reaction and use the energy from ATP --> ADP + Pi. These processes are often exergonic and irreversible.

Can enzymes be used once?
Enzymes are biological catalysts, and like all catalysts they have the property of affecting some chemical reaction (normally, either speeding it up or slowing it down) without being used up or altered in the process. They can be re-used. Indeed, it is often necessary to use some antagonistic enzyme to halt the action of a given enzyme when it has done enough of what it is supposed to do.
Is it true or false catalysts speed chemical reactions but are not changed by them?
True. That's one of the reasons you use them.

Could dilute sulphuric acid be used as catalyst?
There are many chemical processes that use sulfuric acid catalysts - refining petroleum is a big one. Most processes that use it, use very concentrated acid because they want the reaction to go quickly.

Industrial process which uses a catalyst?
Catalysts increase the speed of a reaction without taking place in the reaction themselves. This is very useful in industry as it means that chemicals can be made much faster through usually slow chemical reactions, and as the catalysts don't take part in the reaction themselves, they can be reused as much as its needed. Examples of catalysts in industries include the use of the biological catalysts enzymes to brake down substrates in baby foods into smaller simpler molecules. Catalysts lower the activation energy required for a reaction to occur. This will mean that more molecules will have the energy to react. Catalysts allow equilibrium to be established quicker. Catalysts in general lower reaction temperatures leading to lower production costs. Catalysts add to cost e.g. palladium in catalytic converters. Catalysts can be poisoned by waste products eg. Sulphur in petrol and oil can reduce the properties of catalytic converters.

Yes, transition metals used as catalysts. They make good catalysts because they can easily gain and lose electrons unlike the other elements.
How do manufacturers decided which reaction to use in excess in a chemical reaction?
The cheaper reagent is usually the reagent that is used in excess. This procedure is purely for economic reasons.

Why do we use enzymes more than one time?
Enzymes are catalysts and as such play no direct part in a chemical reaction. Enzymes provide active sites for chemical reactions to take place on. They are specific and work best in a narrow band of optimal conditions.Catalysts of all sorts have 2 major advantages of a chemical reaction without them:they speed up the chemical reaction dramaticallythey are reusableAs they are not used up in the reaction new enzymes do not need to be constantly produced which reduces the pressure on resources in the body. It would be wasteful to have to constantly make new enzymes. Similarly in industry it makes economic sense to use catalysts because they can be used over and over.
What is a possible use for an acid?
For neutralizing bases, as catalysts, as dehydrating agents etc.
