Refer to the Galvanic cel below (the contents of each half-cell are written beneath each compartment):

0.10 M MnO4- 0.40 M Cr3+
0.20 M Mn2+ 0.30 M Cr2 O72-
0.010 M H+ 0.010 M H+

The standard reduction potentials are as follows:

MnO4- + 8H+ 5e-----> Mn2+ + 4H2O E = 1.51 V
Cr2 O72- + 14 H+ + 6 e- ----> 2Cr3+ + 7 H2 O E = 1.33 V
