In an aqueous solution of volume 500ml when the reaction given below2Ag^(+)+ 2Ag^(+)+Cu hati Cu^(2) +2AgCu^(2+)+2Ag reached at equilibrium the [Cu^(2+] was xM.When 500 ml of wateris further added, at the equilibrium the [Cu^(2+)] will be

Answer»

`x`
`2x`
less than `x/2`
`(3x)/4`

Solution :After ADDING water equilibrium will SHIFT BACKWARD and NEW concentration will be less than `x/2`
