Question

Give any five characteristics of catalysis

Answer 1

Answer:

Characteristics of Catalysts are as follows:

1. The catalyst remains unchanged (in mass and chemical composition ) in the reaction (Activity of catalyst.)

2. A small quantity of the catalyst is required. e.g. One mole of colloid Pt catalyses 10^8L H_2O_2

3. The catalyst does not change the equilibrium constant. But the equilibrium approaches earlier.

4. Specificity of Catalyst:

The catalyst is specific in nature. It means by the change of catalyst, nature of the products changes or specific catalyst for a specific reaction.

5. The catalyst can not make impossible reaction to occur and does not intiate a reaction
