For the following reactions enthalpy of reactions are
P shown:

W
\( +3 \mathrm{H}_{2} \longrightarrow \) ; \( \Delta \mathrm{H}=-\mathrm{z} \mathrm{kcal} / \mathrm{mol} \)
If resonance energy of benzene \& cyclohexa-1, 3 -diene is \( -36 \mathrm{kcal} / \mathrm{mol} \mathrm{\&}-\mathrm{x} \mathrm{kcal} / \mathrm{mol} \), then find the value of \( (z-x) \) is:
