    Answer: (b) Rate constant increase 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.
