  • question_answer
    A large increase in the rate of a reaction for a rise in temperature is due to           [EAMCET 1980; MP PET 1995]

    A)                 The decrease in the number of collisions

    B)                 The increase in the number of activated molecules

    C)                 The shortening of the mean free path

    D)                 The lowering of the activation energy

    Correct Answer: B

    Solution :

                    The increase in collision frequency brings in an increase in effective collisions and thus rate of reaction increases.
