Question #315625
1. Define heat
of formation/standard heat of formation ΔHfo.
2. Discuss
standard state and give examples (Padolina et al., 1995).
3. State that
values of standard states of formation are important because these are
conveniently used to calculate changes in enthalpy, ΔH of many
reactions.
4. Give
examples that illustrate the use of standard heats of formation in
calculating changes in enthalpy or ΔH of reactions.

Expert's answer
heat of formation, also called standard heat of formation, enthalpy of formation, or standard enthalpy of formation, the amount of heat absorbed or evolved when one mole of a compound is formed from its constituent elements, each substance being in its normal physical state (gas, liquid, or solid).
