Q. A gas $X$ at 1 atm is bubbled through a solution containing a mixture of 1 M $y^{-}$ and 1 M $\mathcal{z}^{-}$ at $25℃.$ If the order of reduction potential is $\mathcal{z >}y > x$ then
A) $y$ will oxidize $x$ and not $\mathcal{\ z}$
B) $y$ will oxidize $x$ and $\mathcal{z}$
C) $y$ will oxidize $\mathcal{z}$ and not $x$
D) $y$ will reduce both $x$ and $\mathcal{z}$
Explanation
(a)
The tendency to gain electron is in the order $\mathcal{z >}y > x$
Thus, $y + e^{-} \rightarrow y^{-}$
$x \rightarrow x^{-} + e^{-}$
