The standard reducution potentials of `Zn^(2+)|Zn,Cu^(2+)|Cu and Ag^(+)|Ag` are respectively `-0.76,0.34` and `0.8V`. The following cells were constructed. `Zn|Zn^(2+)"||"Cu^(2+)|Cu` `Zn|Zn^(2+)"||"Ag^(+)|Ag` `Cu|Cu^(2+)"||"Ag^(+)|Ag` What is the correct order `E_("cell")^(0)` of these cell?A. `bgtcgta`B. `bgtagtc`C. `agtbgtc`D. `cgtagtb` |
