Gibbs free energy equilibrium equation
WebMay 23, 2024 · (1) Δ G ∘ = − R T log K Generally speaking, K in equation (1) is unitless. Its value depends on the specified reference standard states and T (and obviously on the equilibrium activities of reactants and products). Both K and Δ G ∘ change (and are certainly allowed to) if you change the choice of standard states for any species.
