Question

In an aqueous solution of volume `500ml` when the reaction given below `2Ag^(+)+`
`2Ag^(+)+Cu hati Cu^(2) +2Ag` `Cu^(2+)+2Ag` reached at equilibrium the `[Cu^(2+]` was `xM`.When `500 ml` of water is further added, at the equilibrium the `[Cu^(2+)]` will be
A. `x`
B. `2x`
C. less than `x/2`
D. `(3x)/4`

Answer 1

Correct Answer - C
After adding water equilibrium will shift backward and new concentration will be less than `x/2`
