Rate of a reaction can be expressed by Arrhenius equation as:
k=Ae?E /RT
In this equation, E represents
(1) the energy above which all the colliding molecules will react
(2) the energy below which colliding molecules will not react
(3) the total energy of the reacting molecules at a temperature, T
(4) the fraction of molecules with energy greater than the activation energy of the reaction

brilliant tutorials says its 1)

i feel both mean the same . pls help
