View Answer & Solution

Correct answer · Option A

The value of equilibrium constant is changed in the presence of a catalyst in the reaction at equilibrium.

Explanation

A catalyst lowers the activation energy and speeds up both forward and backward reactions equally, leaving the equilibrium constant \( K_c \) unchanged.
