An electrochemical cell is set up where the overall reaction is : Pb2+ + Sn → Pb + Sn.
Calculate the cell potential Ecell,for this process under the following conditions:
a.Standard conditions at both electrodes
b.[Sn2+ ]=0.01 M; [Pb2+]=0.2 M
c.[Sn2+ ]=0.40 M; [Pb2+]=0.005 M
In each case decide the direction in which the reaction will spontaneously speed.
