WebJul 28, 2024 · In processes involving chemical energy changes, all substances must have the same reference state to be able to use the enthalpy of formation consistently. This reference state corresponds to 25°C (77°F) and 10⁵ Pa = 1 bar. Having defined a universal reference state, we can discuss a new term called standard enthalpy of formation.
