$E_{Y}^{0}=+0.5 V$
$E_{Z}^{0}=-3.0 V$
$Z>X>Y$
$\because$ higher the reduction potential, lesser the reducing power.

(આપેલ છે: $\frac{ RT }{ F }$ in $10=0.06$ ) $E _{ Cell }^{o}$ની કિંમત $4$ $volt$ છે.
આપેલ: $E _{ x ^{2+} \mid x }^0=-2.36\,V$
$E _{ Y ^{3+} \mid Y }^0=+0.36\,V$
$\frac{2.303\,RT }{ F }=0.06\,V$
