WebbThe standard enthalpy of formation (standard heat of formation) of a compound is defined as the enthalpy change for the reaction in which elements in their standard states produce products. At 25°C and 100 kPa, the standard state of any element is solid with the following exceptions: Consider a water molecule, H 2 O.
