What is AG for a reaction where AG = -4.5 kJ/mol and Q = 3.2 at 295 K? (R = 8.314 J/mol K) At 355 K, AG = -5.7 kJ/mol for the reaction A (g) 2 B (g). If the partial pressures of A and B are 8.47 atm and 0.110 atm respectively, what is the standard free energy for this reaction at this temperature? At 1120 K, AG = 47.9 kJ/mol for the reaction 3 A (g) + B (g) 2 C (g). If the partial pressures of A, B, and C are 11.5 atm, 8.60 atm, and 0.510 atm respectively, what is the free energy for this reaction?
