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. WebFeb 1, 2024 · The standard enthalpy of formation is 0 when a molecule is at its most stable state. Therefore for some diatomic molecules such as O2, this would be their most stable state. This is because standard enthalpy is changing the molecule into its most stable state meaning O2(g) -> O2(g) which doesn't change at all. list of belgium rivers https://masegurlazubia.com
