Question

What overall effect does adding a catalyst have on a chemical reaction?

Answer 1

Explanation:

A catalyst is a specie which makes the rate of reaction faster without itself getting consumed into the chemical reaction.

A catalyst decrease the activation energy barrier for the chemical reaction so that, reactant molecules with low energy can easily participate into the reaction.

Hence, product formation becomes faster.

Therefore, overall effect of adding a catalyst will have an increase in formation of products.

Answer 2

The overall effect of a catalyst to the reaction is that it lowers the activation energy of a chemical reaction. Catalyst is a substance that speeds a chemical reaction. It is not consumed as the reaction proceeds. A catalyst offers a new route for faster reaction.
