Give the overall balanced reaction, and determine E° for the galvanic cells. Assume that all concentrations are 1.0 M and that all partial pressures are 1.0 atm. (Type your answer using the format CO2 for CO2, (NH4)2CO3 for (NH4)2CO3, [NH4]+ for NH4+, and [Ni(CN)4]2- for Ni(CN)42-. Use the lowest possible coefficients.)

a. H2O2 + 2 H+ + 2 e- ----> 2 H2O E° = 1.78 V

O2 + 2 H+ + 2 e- ----> H2O2 E° = 0.68 V

Balanced Equation:

E°:

b. Mn2+ + 2 e- -----> Mn E° = -1.18 V

Fe3+ + 3 e- -------> Fe E° = -0.036 V
