Writing the formation reaction 4 C s + 4 H g + O g → C 4 H 4 O g Δ H f ∘ = - 6 2 · 0 = Σ reac BE - Σ product BE Σ product BE = Σ reac BE + 6 2 · 0 = 4 × 7 1 7 + 4 × 2 1 8 + 2 4 9 + 6 2 = 2 8 6 8 + 8 7 2 + 2 4 9 + 6 2 = 4 0 5 1 KJ mol - 1 Σ product BE is heat of atomization of product into isolated gaseous atoms. Hence answer is 40.51
