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, .
Enthalpy is defined as the total energy of the reacting materials, which is given by the sum of the internal energy of the system plus the product of the system's pressure and volume.
