An electrochemical cell is made from iron and copper electrodes whose standard reduction potential are - 0.44V and +0.34 V respectively.  Find cell potential at 298 K if concentration of Cu2+ and Fe2+ are 0.01 and 0.1 mol/l respectively.  Also find maximum work obtained from cell.
 

Dear student




Decrease in free energy gives the maximum work done if the free energy change is negative.
                           -dG = Wmax
                            dG =  -nFE

‚Äč                     Wmax  =  2*96500*0.75
                                  =  144750
