Answer #1

Co2+(aq) + 2 Cu+ (aq) --------------> Co(s) + 2 Cu2+(aq)

Eocell = Eored - Eooxidation

          = - 0.28 - (0.153 )

          = - 0.433 V

delta Go = - n F Eocell

               = - 2 x 96485 x - 0.433

               = 83556.0 J

delta Go = - R T ln K

83556 = - 8.314 x 298 x ln K

K = 2.26 x 10^-15

equilibrium constant = 2.26 x 10^-15

G° for this reaction would be greater than zero.
