According to the Arrhenius equation,
A
a high activation energy usually implies a fast reaction
B
rate constant increases with 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, 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.
