  • question_answer A reaction is catalysed by  ?X ?. Here ?X ? [MP PMT 2003]

    A)                 Decreases the rate constant of reaction

    B)                 Does not affect the equilibrium constant of reaction

    C)                 Decreases the enthalpy of reaction

    D)                 Decreases the activation energy

    Correct Answer: D

    Solution :

                    Catalyst reduce the activation energy for reaction and thus increase the rate of reaction.
