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
Wmax = 2*96500*0.75
= 144750
