Carbon dioxide dissolves in water to form carbonic acid. Estimate the thermodynamic equilibrium constant for this reaction using the AG; values in the table. Substance AG; (kJ/mol) -616.1 H,CO, (aq) H,O(1) -237.1 CO,(g) -394.4 K = Carbonic acid then ionizes in water (Kal = 4.5 x 10-/). Ignoring Ka2, estimate K for the overall process by which CO, and H,O form H+ and HCO,. K = What is the pressure of CO, in equilibrium with carbonated water at 25 °C and pH = 4.57? atm Pco
