ΔHf^o is the enthalpy formation under standard conditions (so 1 atm, 1 mol, and and 278 K) whereas ΔHf just refers to enthalpy formation. ΔHf^o is otherwise known as standard reaction enthalpy for a substance.

Return to “Reaction Enthalpies (e.g., Using Hess’s Law, Bond Enthalpies, Standard Enthalpies of Formation)”
