Solution

The correct option is C a – (iv) b – (i) c – (v) d – (iii) e – (ii)

Activation energy: the minimum quantity of energy which the reacting species must possess in order to undergo a specified reaction.
Change in enthalpy is the difference between the potential energies of products and of reactants.
The activation energy for the reverse reaction is the sum of the enthalpy (delta H) and the activation energy (Eact) for the forward reaction.

a - (iv) Potential Energy of Reactants
b - (i) Activation energy of forward reaction
c - (v) Potential energy of Products
d - (iii) Activation energy of backward reaction
e - (ii) Change in enthalpy
