The potential of electrodes Cu2+ (aq) | Cu(s) is  ϕ1 = 0.337 V , and  Cu2+ (aq), Cu+ (aq) | Pt  is ϕ2 = 0.153 V , respectively.  a) Calculate the value of ϕ0 for electrode Cu+(aq) | Cu(s). [Hint: Write half reactions for the above two electrodes, then derive the target electrode.] b) Calculate the equilibrium constant Ka0 for the reaction Cu(s) + Cu2+ (aq) = 2Cu+ (aq) at 298.15K. [Hint: Based on the reaction, design a cell with two electrodes and verify that the two half reactions will give you the target reaction. Then calculate the cell potential.]
