    On the velocity in a reversible reaction, the correct explanation of the effect of catalyst is            [MP PMT 1987]

    A)                 It provides a new reaction path of low activation energy

    B)                 It increases the kinetic energy of reacting molecules

    C)                 It displaces the equilibrium state on right side

    D)                 It decreases the velocity of backward reaction

    Correct Answer: A

    Solution :

              Effect of catalyst is that it attains equilibrium quickly by providing a new reaction path of low activation energy. It does not alter the state of equilibrium.
