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.

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.
