A chemical reaction has catalyst X. Hence X

A

does not affect equilibrium constant of the reaction

B

decreases rate constant of the reaction

C

reduces enthalpy of reaction

D

increases activation energy of the reaction

Text Solution

Verified by Experts

The correct Answer is:
A
A catalyst cannot change the state of equilibrium and hence equilibrium constant because the rate of forward and backward reaction are effected to the same extent.
