In a 1.0 L aqueous solution when the reaction `2Ag^(+)(aq) + Cu(s) rarr Cu^(2+)(aq) + 2Ag(s)` reaches equilibrium,`[Cu^(2+)] = xM "and" [Ag^(+)] = yM` If the volume of solution is doubled by adding water, then at equilibrium :

A

`[Cu^(2+)] = x/2 M, [Ag^(+)] = Y/2 M`

B

`[Cu^(2+)] gt x/2 M, [Ag^(+)] gt Y/2 M`

C

`[Cu^(2+)] lt x/2 M, [Ag^(+)] gt Y/2 M`

D

`[Cu^(2+)] lt x/2 M, [Ag^(+)] lt Y/2 M`

Text Solution

Verified by Experts

The correct Answer is:
C
Consider the equation : `2Ag^(+)(aq) + Cu(s) rarr Cu^(2+)(aq) + 2Ag(s)`
At equilibrium : `[Cu^(2+)] = xM , [Ag^(+)] = yM`
`K_(eq) = K_(c) = [Cu^(2+)]/[Ag^(+)]^(2) = x/y^(2)`
