A catalyst :

A

increases the average kinetic energy of the reacting molecules

B

decreases the value of enthalpy change in the reaction

C

reduces the time required for reaching the equilibrium state in the reaction

D

decreases the rate of backward reaction

Text Solution

Verified by Experts

The correct Answer is:
C
Catalyst affects both the reactions, i.e., forward and backward reactions, so equilibrium is established in lesser time.
