Refer to the galvanic cell 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 Cr2O72–
0.010 M H+                              0.010 M H+
The standard reduction potentials are as follows:
MnO4 + 8H+ + 5e→ Mn2+ + 4H2O, E° = 1.51 V
Cr2O72– + 14H+ + 6e→ 2Cr3+ + 7H2O, E° = 1.33 V

In which direction do electrons flow in the external circuit?

Reference: 18-3


left to right
right to left
no current flows; the cell is at equilibrium
no current flows; the cell is not at equilibrium
None of these are correct.
