A gas $\mathrm{X}$ at $1 \mathrm{~atm}$ is bubbled through a solution containing a mixture of $1 \mathrm{M} \mathrm{Y}^{-}$ and $\mathrm{M} Z^{-}$ at $25^{\circ} \mathrm{C}$. If the reduction potential of $Z>Y>X$, then,
$\mathrm{Y}$ will oxidize $\mathrm{X}$ and $\operatorname{not} \mathrm{Z}$
$Y$ will oxidize $Z$ and $\operatorname{not} X$
$\mathrm{Y}$ will oxidize both $\mathrm{X}$ and $\mathrm{Z}$
$\mathrm{Y}$ will reduce both $\mathrm{X}$ and $\mathrm{Z}$
Solution
The given order of reduction potentials (or tendencies) is $Z>Y>X$. A spontaneous reaction will have the following characteristics Z reduced and Y oxidised Z reduced and X oxidised Y reduced and $X$ oxidised Hence, Y will oxidise $X$ and $\operatorname{not} Z .$
