Enter your answer in the provided box. For reactions carried out under standard-state conditions, the equation ΔG = ΔH − TΔS becomes ΔG o = H o − TΔS o . Assuming ΔH o and ΔS o are independent of temperature, one can derive the equation: ln K2 K1 = ΔH o R ( T2 − T1 T1T2 ) where K1 and K2 are the equilibrium constants at T1 and T2, respectively. Given that at 25.0°C, Kc is 4.63 ×...
