Question
Calculate AG° and K at 25°C for the reactions. 7H2O + 2 Cr+ + 3 Cl2 = Cr2 07²- + 6 Cl¯ + 14H = 0.03 V cel a. AG° = kJ K = Cu²+ (aq) + Ba(s) = Ba2+ (aq) + Cu(s) e° = 3.24 V b. AG° : kJ K = Cl2 (g) + 2 Br (aq) = Br2 (g) + 2 Cl¯ (ag) e° = 0.27 V C. AG° = kJ K = 3H2 O(1) + 5 IO4 (ag) + 2 Mn²+ (aq) = 5 IO3 (aq) + 2 MnO4¯(ag) + 6H† (ag) d. 0.09 V ´cell AG° = kJ K =
