For reactions carried out under standard-state conditions, the equation ΔG = ΔH − TΔS becomes ΔG° = H° − TΔS°. Assuming ΔH° and ΔS° are independent of temperature, one can derive the equation: ln( K2 K1 ) = ΔH° R ( T2 − T1 T1T2 ) where K1 and K2 are the equilibrium constants at T1 and T2, respectively.
