Problem

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

            B)        –0.11V

            C)        +0.28 V

            D)        +0.272 V

            E)         –0. 299 V
