The free-energy change (?G) for a simple reaction, A ? B, is 0 kJ/mole at 37°C when the concentrations of A and B are 10 M and 0.1 M, respectively. What is the free-energy change for the reaction when the concentrations of A and B are instead 0.01 M and 1 M, respectively? Recall that ?G° = -5.9 × log(K?q). Write down your answer as a number with the appropriate sign (+ or -) and in kJ/mole, e.g. +11.8 kJ/mole.
