WebSo, enthalpy of iron oxide at 1000K is enthalpy of iron oxide at 298K + integration of Cp of iron oxide from 298K to 1000K. Enthalpy of solid iron and oxygen molecule at 1000K can be written similarly. Rearrange the equation so that the enthalpies at 298K come together. This is the heat of formation of iron oxide at reference state, Hf nought ...

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. Its symbo…
