WebEnthalpy change (∆H) is the amount of heat energy transferred during a chemical reaction at constant pressure. We also measure enthalpy change in J mol-1 or kJ mol-1. Whenever a chemical reaction occurs at constant pressure, heat energy is absorbed or released, and thus an enthalpy change takes place.
