We're being asked to determine the standard reduction potential of Rb/Rb+ half­-cell when the cell potential is +0.02 V and the half-­cell potential of Li+/Li is -3.05 V where the cell notation is

Rb | Rb +|| Li +| Li

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