Standard enthalpy of reaction

（重定向自Heat of Reaction）

The standard enthalpy of reaction (denoted ΔH_r) is the enthalpy change that occurs in a system when one mole of matter is transformed by a chemical reaction under standard conditions.

For a generic chemical reaction

the standard enthalpy of reaction ΔH_r is related to the standard enthalpy of formation ΔH_f of the reactants and products by the following equation:
