Ans : (a) ∆H = 0
Solution :
A reaction having equal energies of activation for forward and reverse reaction has ∆H = 0.
The enthalpy change for a reaction is the difference in the energies of activation for forward and reverse reactions.
When energies of activation for forward and reverse reactions are equal, the difference is zero.
