Hey! Here is your answer.

1. Catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

2. Promoter is a substance added to a solid catalyst to improve its performance in a chemical reaction.

3. Inhibitor is a substance that decreases the rate of, or prevents, a chemical reaction.

4. Substances which destroy the activity of the catalyst by their presence are known as catalytic poisons.


Characteristics of Catalysis:

(1) A catalyst remains unchanged in mass and chemical composition at the end of the reaction.

(2) A small quantity of the catalyst is generally sufficient to catalyses almost unlimited reactions.

(3) The catalyst can not initiate the reaction.

(4) The catalyst is generally specific in nature.

(5) The catalyst can not change the position of equilibrium .


Hope this helps.
