At 25.0 °C, the reaction CO2(g) + H2O(l) ⇔ H+(aq) + HCO3-(aq) is at equilibrium when PCO2 = 3.50 mbar, [H2O] = 55.5 mol L-1, [H+] = 39.8 µmol L-1, and [HCO3-] = 1.28 mmol L-1. Then an additional 4.00 mbar of CO2 is added to the system. Calculate ΔGrxn in kJ mol-1. (R = 8.3145 J mol-1 K-1) (Hint: you will need to first perform a calculation under equilibrium conditions, and then a second calculation under non-equilibrium conditions.)
