For the cell reaction?

Question

Cu2+(aq) + Zn(s) -> Cu(s) + Zn2+(aq) , E cell = 1.10V.

Use the Nernst equation to determine Ecell when the molar concentrations of Zn2+ and Cu2+ are 1.0M and 1.0*10^-7M, respectively.

Answer 1

n=no. of electron

Ecell  = E(standard cell potential) - {2.303RT log[ (Zn2+)/(Cu2+)}/nF}

        =1.10+0.2065

       =1.3065 v
