The standard reduction potential of Pb and Zn electrodes are `-0.126` and `-0.763 V` respectively. The cell equation will beA. `Pb^(2+)+Zn rarr Pb+Zn^(2+)`B. `Pb^(4+)+2 Zn rarr Pb+2 Zn^(2+)`C. `Zn^(2+)+Pb rarr Zn+Pb^(2+)`D. None of the above |

Answer» Correct Answer - C The `E_(red)^(@)` of `Zn` is lower than that of `Pb`, hence `Zn` is a better reducing agent than `Pb`. `:.` The correct cell reaction will be `Zn^(2+)+Pb rarr Zn+Pb^(2+)` |
