Standard enthalpy of combustion (ΔcH0)

Consider the reaction

C2H2(g)+52 O2(g)⟶2 CO2(g)+H2O(l),ΔrH0=−1300 kJ\mathrm{C_2H_2(g)} + \frac{5}{2}\,\mathrm{O_2(g)} \longrightarrow 2\,\mathrm{CO_2(g)} + \mathrm{H_2O}(l), \quad \Delta_r H^0 = -1300\ \mathrm{kJ}

In the above reaction, the standard enthalpy change of the oxidation reaction, -1300 kJ, is the standard enthalpy of combustion of C2_2H2_2(g). …
