1.

The cell, `Zn|Zn^(2+)(1M)||Cu^(2+)(1M)|Cu,(E_(cell)=1.10V)`, was allowed to be completely discharged at 298K. The realtive concentration of `Zn^(2+)` to `Cu^(2+),((Zn^(2+)])/([Cu^(2+)]))` isA. `9.65xx10^(4)`B. antilog 24.08C. `37.3`D. `10^(37.3)`

Answer» Correct Answer - B
The cell reaction is: `Zn+Cu^(2+)toZn^(2+)+Cu` when the cell is completely discharged, `E_(cell)^(@)=(0.0591)/(2)"log"([Zn^(2+)])/([Cu^(2+)])`
i.e., `1.10=(0.591)/(2)"log"([Zn^(2+)])/([Cu^(2+)])`
or `([Zn^(2+)])/([Cu^(2+)])=37.3` or `([Zn^(2+)])/([Cu^(2+)])=10^(37.3)`
