WebJun 9, 2024 · The symbol for free energy is \(G\), in honor of American scientist Josiah Gibbs (1839 - 1903), who made many contributions to thermodynamics. The change in Gibbs free energy is equal to the change in enthalpy minus the mathematical product of the change in entropy multiplied by the Kelvin temperature. WebEquilibria, ∆G, ∆H and ∆S In a wide range of situations, we will see that understanding ∆G, ∆H and ∆S can help us understand where an equilibrium lies and often allow us to control whether the reactants or products are favored.
