Heat of formation oxygen gas

Other names: Molecular oxygen Oxygen molecule Pure oxygen O2 Liquid oxygen. Enthalpy of reaction at standard conditions (nominally 298.15 K, 1 atm.). The standard enthalpy of formation of oxygen gas is zero. Here’s the reason why.Top contributors to the provenance of ?fH° of O (g, singlet) 47.7, O2 (g) ? 2 O (g), ?rH°(0 K) = 41269.2 ± 0.5 cm-1 24.0, O2 (g) ? O+ (g) + O- (g), ?rH°(0 K). Most Influential reactions involving O2 (g, singlet) 0.897, 13.7 · ?rH°(0 K) = 7892.01766 ± 0.0020 cm-1 0.035, 13.4 · ?rH°(0 K) = 7892.0214 ± 0.010 cm-1 0.035. The standard enthalpy of formation of any element in its standard state is zero by definition. For example, although oxygen can exist as.
