WebbΔG° = ΔH° − TΔS°. So, if we want to calculate the standard Gibbs free energy of formation of a species (ΔG ƒ °), we will need to know the standard enthalpy of formation of the species (ΔH ƒ °), the temperature (T in kelvin), and the standard absolute entropy change for the formation of the species (ΔS ƒ °). Then we can write ... WebbTable 7.1 “Enthalpies of Formation for Various Substances” lists some enthalpies of formation for a variety of substances; in some cases, however, phases can be important (e.g., for H 2 O).
