Voltage for a Standard Cell

Using the electrode potentials in appendix C3 of your text, calculate the voltage for a standard cell using the following reaction:

H2O2 + MnO2 + H+ → Mn+2 + O2 + H2O

Solution Preview

First, we have to find the two half-reactions:

MnO2 + 4H+ + 2e- → Mn+2 + 2H2O (E = 1.23 V)

O2 + 2H+ + 2e- → H2O2 (E = 0.682 V)

Of course, the second reaction needs to be switched around. When we do, we ...
