A gas X at 1 atm is bubbled through a solution containing a mixture of 1 M Y^- and 1 M Z^- at 25^ . If the order of reduction potential of the respective couples is Z>Y>X, then

JEE Main Chemistry question

A gas X at 1 atm is bubbled through a solution containing a mixture of 1 M and 1 M at C. If the order of reduction potential of the respective couples is , then

(A)Y will oxidize X and not ZCorrect
(B)Y will oxidize both X and Z
(C)Y will oxidize Z and not X
(D)Y will reduce both X and Z

Answer: (A)

Solution

A couple with a higher reduction potential can oxidize the reduced (anion) form of a couple with a lower reduction potential, but not of one with a higher reduction potential. Since the order is , the intermediate
