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

(A) catalyst decreases the activation energies of both the forward and backward reactions by the same amount. Therefore,it speeds up both the forward and backward reactions at the same rate. As a result,the equilibrium constant $(K_{eq})$ remains unaffected by the presence of a catalyst at a given temperature. Thus,the statement that the equilibrium constant changes is incorrect.
