What is the purpose of a catalyst?

Answer 1

a catalyst provides a different path for a reaction to occur

To lower the activation energy of a reaction

Answer 2

Catalyst is the agent which alter the rat of chemical reactions.Catalyst is not consumed by the reaction as the other reactants.

those catalyst which increases or speed up the reaction are known as positive catalyst.

Those slows the reaction are known as negative catalyst.

Catalyst may act by decreasing activation energy of reaction or by choosing an alternate pathway for the reaction.

Answer 3

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.

Answer 4

the function is to lower the energy of activation

Answer 5

speed up reaction and to lower activation energy

Answer 6

To lower the activation energy and to increase the rate of a chemical reaction.

Answer 7

A catalyst speeds up a chemical reaction by providing an alternative pathway with lower activation energy. It remains unchanged at the end of the reaction and can be used repeatedly.
