(A) catalyst provides an alternative pathway with lower activation energy for both forward and backward reactions equally. Therefore,it does not affect the equilibrium constant or the position of equilibrium.$(b)$ Boltzmann and Maxwell used the kinetic theory of gases and the concept of molecular collisions to explain the distribution of molecular energies and the rate of reaction.
