Explain the things that happen in the second and third steps in `N_2` Cycle.

A reaction occurs in three steps . The rate constants of the first , second and third steps of the reaction are k_(1), k_(2) and k_(3) respectively and the overall rate constant of the reaction is k=k_(1)k_(2)//k_(3) . If the activation energies of the first , second and third step of the reaction are 30, 44 and 56"kJ.mol"^(-1) respectively , then the overall activation energy of the reaction ("in kJ.mol") is -
