Please let me know how we can solve this. Thanks. In chemistry and thermodynamics, the standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements in their reference state, with all substances in their standard states. The standard pressure value p = 10 Pa (= 100 kPa = 1 bar) is recommended by IUPAC, although prior to 1982 the value 1.00 atm (101.325 kPa) was used. There is no standard temperature.

WebEnthalpy is a state function, defined by the internal energy (E), the pressure (P) and volume (V) of a system: H = E + PV and ΔH = ΔE + Δ (PV) For enthalpy, there are no method to determine absolute values, only enthalpy changes (ΔH values) can be measured. Then it is important to have a common and well defined reference state. Web1.Enthalpy is an extensive property. The magnitude of ΔH is dependent upon the amounts of reactants consumed.
