Use bond energies to estimate \( \Delta H \) for the combustion for four moles of acetylene \( (\mathrm{H}-\mathrm{C} \equiv \mathrm{C}-\mathrm{H}) \). \[ \underset{k J}{\mathrm{C}_{2} \mathrm{H}_{2}(g)+5 / 2 \mathrm{O}_{2}(g) \rightarrow 2 \mathrm{CO}_{2}(g)+\mathrm{H}_{2} \mathrm{O}(g)} \]
Reaction is C2H2(g) + 5/2O2(g) 2CO2(g) + H2O(g) type of bond Bond energy Number of bond in reactant Number of bond in product C - H 413 KJ/mol 2 0 C C 839 KJ/mol 1 0 O
