MCQ
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 occure, irrespective of their energy.
