For reactions carried out under standard-state conditions, Equation 18.10 takes the form ∆G° = ΔH°‒ TΔS°.

(a) Assuming ∆H° and ∆S° are independent of temperature, derive the equation

where K1 and K2 are the equilibrium constants at T1 and T2, respectively, (b) Given that at 25°C Kc is 4.63 X 10−3 for the reaction

calculate the equilibrium constant at 65°C.
