a) For a reaction with AH = -152.6 kJ mol-¹ and AS° = -543.8 J K-¹ mol-¹ at 25 °C, how will AG⁰ change if the reaction temperature is increased? Explain your answer. b) Calculate the equilibrium constant for the reaction at 80 °C, showing your working (assume AH and AS are temperature independent).
