2) The equilibrium constant Keq for the reaction A B is 1 x 105 at room temperature (25°C). a) You make a solution containing compound A at a concentration of 1 M and compound B at a concentration of 1 mM of B, and let the reaction proceed to equilibrium. What are the equilibrium concentrations of A and B? b) Calculate the standard free-energy change (AG) for this reaction. c) What is the standard free-energy change (AG) for the inverse reaction (BA)? d) With the provided information, can you estimate how long will it take this reaction to reach equilibrium? e) In a reaction cell that has not reached equilibrium, we have the following instantaneous concentrations: [A] = 0.05 mM; [B] = 15 mM. Calculate the actual free-energy change (AG) for the system as it reaches equilibrium at 25°C.
