Acetylene burns in air to produce carbon dioxide and water: C2H2(g) + 5/2O2(g) → 2CO2(g) + H2O(l). Use the following thermochemical equations to obtain ΔGr0 at 25 °C for the combustion of acetylene: C2H2(g) + 3H2(g) → 2CH4(g) ΔGr0 = −310.7 kJ/mol at 25 °C CH4(g) + 2O2(g) → CO2(g) + 2H2O(l) ΔGr0 = −817.97 kJ/mol at 25 °C H2(g) + 1/2O2(g) → H2O(l). ΔGr0 = −237.18 kJ/mol at 25 °C
