Electrochemical Cells

Reduction potential values of

cell reaction is ;

              $Cu\left(s\right)+S{n}_{\left(aq\right)}^{2+}\to C{u}_{\left(aq\right)}^{++}+S{n}_{\left(s\right)}$  

              $Q=\frac{\left[C{u}^{++}\right]}{\left[S{n}^{++}\right]}=\frac{0.01}{0.001}andn=2$  

              $E_{cell}=E_{cell}^o-\frac{0.059}{2}log\frac{0.01}{0.001}$  

              $=-0.48-\frac{0.059}{2}log10=-0.509$  

              $=983.33*10^{-1}KJ/mole$  

              Nearest integer = 983
