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, .
Example: Standard Enthalpy (Heat) of Formation of Water. This means that 286 kJ of energy is released when liquid water, H. This reaction is written as: H2(g) + &#189O2(g) â H2O(l) &nbsp &nbsp ÎHfo = -286 kJ mol-1. The standard enthalpy (heat) of formation of water vapour at 298K (25 o) is -242 kJ mol -1.
