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, .
Reaction enthalpy change occurs when the amount of reactants in the chemical equation react under standard conditions to create the products. Formation enthalpy change occurs when one mole of a compound is formed from its elements that are in their standard states and in standard conditions. Combustion enthalpy change occurs when one mole of an element reacts completely with oxygen under standard conditions.
