In an aqueous solution of volume 500 ml ...

In an aqueous solution of volume `500 ml` when the reaction `2Ag^(+)(aq)+Cu(s) hArr Cu^(2+)(aq)+2Ag(s)` reached equilibrium, the `[Cu^(2+)]` was `'a'M`. If `500 ml` water is further added, at the equilibrium `[Cu^(2+)]` will be `:`

A

`'a'//2M`

B

`'a'M`

C

between `'a'` and `'a//2'M`

D

less than `'a//2'`

Text Solution
