E=E°+(0.059/n) log ([ Cu +2]/[ Zn +2]) [ n =2] E = E °+(0.059/2) log ((0.2)/(0.002)) If ( Cu +2) uparrow= E uparrow

Q. The maximum current can be drawn from which of the following cells?

$Z n_{(s)} ∣ ∣ Z n^{2 +}_{(0.2 M)} ∥ C u^{2 +}_{(O .2 M)} ∣ ∣ C u_{(s)}$

$Z n_{(s)} ∣ ∣ Z n^{2 +}_{(0.002 M)} ∥ C u^{2 +}_{(0.2 M)} ∣ ∣ C u_{(s)}$

$Z n_{(s)} ∣ ∣ Z n^{2 +}_{(0.2 M)} ∥ C u^{2 +}_{(0.002 M)} ∣ ∣ C u_{(s)}$

All of these

$E = E^{\circ} + \frac{0.059}{n} lo g \frac{[ C u ^{+ 2} ]}{[ Z n ^{+ 2} ]}$
$[n = 2]$
$E = E^{\circ} + \frac{0.059}{2} lo g \frac{( 0.2 )}{( 0.002 )}$
If $(C u^{+ 2}) ↑= E ↑$
