The gas`X` at `1 atm` is bubbled through a solution containing a mixture of `1M Y^(-)` and `1M Z^(-)` at `25^(@)C` . If the order of reduction potential is `ZgtYgtX`, then

Options

A. Y will oxidise X and not Z
B. Y will oxidise Z and X
C. Y will oxidise both X and Z
D. Y will reduce both X and Z

Answer

A

Explanation

Electrode potential order `Z gt Y gt X`.
A spontaneous reaction will have the following characteristics:
Z reduced and X oxidised
Y reduced and X oxidised
Z reduced and Y oxidised
Hence, Y will oxidise X and not Z.
