Gibbs Free Energy - Softschools.com Enduring Understanding 5.E.2: Gibbs Free Energy. Gibbs Free Energy is used to determine whether a reaction is favored or disfavored. It is given by the equation: ΔG = ΔH - TΔS. Where ΔH is the enthalpy change, ΔS is the entropy change, and T is the temperature. If ΔG < 0, then products are favored at equilibrium (K > 1), and the forward ...
