According to the Arrhenius equation

Answer»

A high activation energy usually implies a fast reaction
Rate constant INCREASES with increase in temperature . This is due to a greater NUMBER of collisions whose energy exceeds the activation energy
Higher the magnitude of activation energy , stronger is the temperature DEPENDENCE of the rate constant
The pre-exponential factor is a measure of the rate at which collisions OCCUR , irrespective of their energy
