    The reason for almost doubling the rate of reaction on increasing the temperature of the reaction system by \[{{10}^{o}}C\] is:

    A)  the value of threshold energy increases

    B)  collision frequency increases

    C)  the fraction of the molecule having energy equal to threshold energy or more increases

    D)  activation energy decreases

    Correct Answer: B

    Solution :

    On increasing the temperature the kinetic energy of the reacting molecules increasing and hence number of collision increases. So that rate of reaction will be increased.
