Chao and Rossini, 1965 Chao, J.; Rossini, F.D., … The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it. The calorific value is the total energy released as heat when a substance undergoes complete combustion with oxygen under standard conditions. The chemical reaction is typically a hydrocarbon or other organic molecule reacting with oxygen to form carbon dioxide and water an…

WebbStandard enthalpy of combustionis the enthalpy change when one mole of an organic compound reacts with molecular oxygen(O2) to form carbon dioxide and liquid water. For example, the standard enthalpy of combustion of ethanegas refers to the reaction C2H6(g) + (7/2) O2(g) → 2 CO2(g) + 3 H2O (l).
