The equilibrium constant (K) for a reaction at a particular temperature is related to the standard Gibbs free energy change (ΔG°) by:
A. ΔG° = -RT ln(K)
B. ΔG° = RT ln(K)
C. ΔG° = K/RT
D. ΔG° = -K/RT
The relationship is ΔG° = -RT ln(K), where R is the gas constant and T is the absolute temperature.
