The role of catalyst in a chemical reaction is :

A

To help attain equilibrium in a shorter time.

B

To lower the activation energy.

C

To shift the equilibrium in such a way as to increase the concentration of the product

D

Both (a) & (b)

Text Solution

Verified by Experts

The correct Answer is:
D
Due to catalyst, the state of equilibrium is not affected i.e., no shift will occur is catalyst lower the activation energy of both the forward & reverse reaction by same amount, thus, altering the forward & reverse rate equally & hence, the equilibrium will be attaine faster.
