For the reaction:
Sn 4+(aq)+ 2 Cu+(aq) → 2 Cu2+(aq)+ Sn2+(aq)
If the concentrations of the reactants are: [Sn2+] is 0.66 M, [Cu+] = [0.03M], [Sn4+] = 0. 01M, [Cu2+] = [0.5M] what is the cell potential?
E o1/2 cell
2e– + Sn4+(aq) → Sn2+(aq) +0.13
e– + Cu2+(aq) → Cu1+(aq) +0.15
A) –0.146 V
C) +0.28 V
D) +0.272 V
E) –0. 299 V
