Gibbs free energy is the maximum possible work given by chemical reactions at constant pressure and temperature. Gibbs free energy can be used to determine the spontaneity of a reaction

Reaction

SO₃ + H₂O ⇒ H₂SO₄ ΔG° = -90.5 kJ

Formula

[tex]\tt \Delta G^o=-RT~ln~K\\\\-90.5\times 10^3~J=-8.3145~J/mol.K\times 298~K~ln~K\\\\ln~K=36.5255\rightarrow K=e^{36.5255}=7.3\times 10^{15}[/tex]
