A gas X at 1 atm is bubblcd through a soluution containing a mixture of `1 M Y ^(-) and 1 M Z ^(-) at 25^(@)C.` If the rcduction potential tial of `Z gt Y gt X,` then,

Options

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

Answer

A

Explanation

The given order of reduction potentials (or tendencies) IS `Zgt Y gt X. A` spontacous reaction will have the followig characteristices
Z reduced andY oxidised
Z reduced and X oxidised
Y reduced and X oxidised
Hence, Y will oxidise X and not Z.
