The `E^(c-)` for `Cu^(2+)//Cu^(o+),Cu^(o+)//Cu,Cu^(2+)//Cu,` are `0.15V,0.50V` and `0.325V`, respectively. The redox cell showing redox reaction `2Cu^(o+) rarr Cu^(2+)+Cu` is made. `E^(c-)` of this cell reaction and `DeltaG^(c-)` may beA. `E^(c-)=0.175V or E^(c-)=0.350V`B. `n=1 or 2`C. `Delta G^(c-)=-33.775k J`D. All of these |
