We're being asked to determine the standard reduction potential of Ga3+/Ga half­-cell when the cell potential is 0.90 V and the half-­cell potential of Cu2+/Cu is +0.34 V.

3 Cu2+(aq) + 2 Ga(s) ⇌ 3 Cu(s) + 2 Ga3+(aq)

To determine the standard cell potential of the other half-cell reaction, we must identify which reaction is present in the anode and cathode
