According to the Arrhenius equation,

(A) A high activation energy usually implies a fast reaction

(B) Rate constant increases with an increase in temperature. This is due to a greater number of collisions whose energy exceeds the activation energy.

(C) Higher the magnitude of activation energy, the stronger is the temperature dependence of the rate constant.

(D) The pre-exponential factor is a measure of the rate at which collisions occur, irrespective of their energy.
