Solution

The correct option is A $10^{37.3}$
If it is allowed to completely discharge, $E_{c e l l} = 0$ .

$E_{c e l l}^{\circ} - \frac{0.059}{2} l o g \frac{[Z n^{2 +}]}{[C u^{2 +}]} = 0$
$∴ l o g \frac{[Z n^{2 +}]}{[C u^{2 +}]} = \frac{1.10 \times 2}{0.059}$
$∴ \frac{[Z n^{2 +}]}{[C u^{2 +}]} = 10^{37.3}$

Hence, option D is correct.

The cell, Zn|Zn2+(1M)||Cu2+(1M)|Cu, was allowed to be completely discharged at 298 K. The relative concentration of Zn2+ to Cu2+([Zn2+][Cu2+]) is :[E0cell=1.10V]

The correct option is A 1037.3If it is allowed to completely discharge, Ecell=0.E∘cell−0.0592log[Zn2+][Cu2+]=0∴log[Zn2+][Cu2+]=1.10×20.059∴[Zn2+][Cu2+]=1037.3Hence, option D is correct.
