Question

Calculate Delta G degree and K at 25degree C for the following galvanic cell reactions. Cl2 + 2e- rightarrow 2 Cl- C degree = 1.36 V Br2 + 2 e- rightarrow 2 Br- C degree = 1.09 V Delta G degree kJ K + 8H+ + 5 e- rightarrow Mn2+ + 4 H2O C degree = 1.51 V + 2 H+ + 2e- rightarrow + H2O C degree = 1.60 V Delta G degree kJ K H2O2 + 2 H+ + 2 e- rightarrow 2 H2O C degree = 1.78 V O2 + 2 H+ + 2 e- rightarrow 2 H2O2 C degree = 0.68 V Delta G degree kJ K Mn2+ + 2 e- rightarrow Mn C degree = -1.18 V Fe3+ + 3e- rightarrow Fe C degree = -0.036 V Delta G degree kJ K
