\textbf{88 --} Considering the thermochemical reaction: $\Delta H = \blacksquare\blacksquare\blacksquare +65 \text{ kJ}$, $2\text{CH}_2(g) \longrightarrow \text{C}_2\text{H}_4(g) + \text{H}_2(g)$, the average enthalpy of the $\text{C}{=}\text{H}$ bond per mole is how many kilojoules? (The enthalpies of $\text{H}{-}\text{H}$ and $\text{C}{=}\text{C}$ bonds are 435 and 348 kJ per mole, respectively.)
