Expert Answer
In the given cell the reduction of Sn 2+ ions takes pace and also the oxidation of copper metal to copper ions takes place.Eo cell is
                               E°cell   = E°cathode      -   E°anode
                               E°cell   = E° Sn2+ / Sn -  E°  Cu2+ / Cu
                                                                = -0.14 V – ( -0.34) = 0.20V
                                                              Δ Go = - nFEo celll  

                                                                        = -2 x 96500 x 0.20 V = -38600 J
