Enthalpy of Formation. The (molar) enthalpy of formation is the heat released ( ) or absorbed ( ) in a chemical reaction at constant pressure when simple substances combine into a more complex substance. At standard conditions of pressure and temperature (1 atm and 298 K), it is denoted . For elements in their standard states, .
The standard enthalpy of formation is measured in units of energy per amount of substance, usually stated in kilojoule per mole (kJ mol â1), but also in calorie per mole, joule per mole or kilocalorie per gram (any combination of these units conforming to the energy per mass or amount guideline).f the standard enthalpy of the products is less than the standard enthalpy of the reactants, the standard enthalpy of reaction will be negative. This implies that the reaction is exothermic. The converse is also true; the standard enthalpy of reaction will be positive for an endothermic reaction.
