Q53 / 180 · KCET 2025 · Chemistry

Catalysts are used to increase the rate of a chemical reaction. Because it

A
Increases the activation energy of the reaction
Correct answer
B
Decreases the activation energy of the reaction
C
Brings about improper orientation of reactant molecules
D
Increases the potential energy barrier

Solution

Positive catalyst decreases the activation energy to increase rate of reaction.

Hence, the correct answer is option: 'B'.
