Knowledge Check

  • For a certain reaction a large fraction of molecules has energy more than the threshold energy, still the rate of reaction is very slow. The possible reason for this could be that

    A
    the colliding molecules could be large in size
    B
    the colliding molecules must not be properly oriented for effective collisions
    C
    the rate of reaction could be independent of the energy
    D
    one of the reactant cound be in excess.
