3. A galvanic cell is constructed comprising cadmium anode and nickel cathode: Cd (s) + Ni²+ (aq) → Cd²+ (aq) + Ni (s) The cell potential when [Cd²+] = [Ni²+] = 1 M is 0.170 V, and the cell potential is 0.240 V when the [Ni²+] is maintained at 1 M but [Cd²+] is changed, maintaining a temperature of 298 K in both cases. (i) Determine the Gibbs energy of the cell under both the original and new conditions. (ii) Calculate the concentration of Cd²+ under the new conditions. You may use concentrations/partial pressures in place of activities.
