Calculate the standard cell potential Delta G of the following reaction: Cd(s)+Cl2(g) --> 2Cl- + Cd2+(s)

Calculate the standard cell potential Delta G of the following reaction:

Cd(s)+Cl2(g) --> 2Cl- + Cd2+(s)

Solutions

Expert Solution

Cd(s)+Cl2(g) -----------> 2Cl- + Cd2+(s)

Oxidation : Cd (s)   -----------------> Cd+2 + 2e-           Eo = - 0.403 V

Reduction : Cl2 (g) + 2e-   ---------------> 2 Cl-               Eo = 1.36 V

Eocell = Eored - Eooxidation

          = 1.36 - (-0.403)

Eocell = 1.763 V

delta Go = - n F Eocell

              = - 2 x 96485 x 1.763 x 10^-3

delta Go = - 340.2 kJ/mol
