Question

Which action would reduce the activation energy of a chemical reaction?

Answer 1

Answer: Option (A) is the correct answer.

Explanation:

A catalyst is a substance which helps in increasing the rate of a reaction without itself getting consumed in the reaction.

A catalyst lowers the activation energy of a reaction so that reactant molecules with less energy can easily participate into the chemical reaction and thus, product formation becomes faster.

Thus, we can conclude that adding a catalyst to the reaction would reduce the activation energy of a chemical reaction.
