Questions are based on the following information.
A voltaic cell is set up to study the reaction below, with two vessels connected by a salt bridge and wire at 25°C: MnO–4 + 3VO2+ + H2O → MnO2 + 6H+ + 3VO+2

The following table provides standard reduction potentials at 25°C for the two relevant half-reactions:
