WebThe standard enthalpy of formation is a measure of the energy released or consumed when one mole of a substance is created under standard conditions from its pure elements. The symbol of the standard enthalpy of formation is ΔH f. Δ = A change in enthalpy. o = A degree signifies that it's a standard enthalpy change. WebMay 9, 2024 · The standard enthalpy of formation of any element in its most stable form is zero by definition. The standard enthalpy of formation of any element in its standard state is zero by definition. For example, although oxygen can exist as ozone (O 3), atomic oxygen (O), and molecular oxygen (O 2), O 2 is the most stable form at 1 atm pressure and 25°C.
