If the concentration of` Y ^(-)` ion in the reaction
`XY_(3(s)) hArr X_(aq)^(+3)+3Y^(-)(aq)` is
decreased by `(1)/(2)` times, then equilibrium `conc^(n)` of
`X^(+3)` will increase by :-

A

2 times

B

4 times

C

8 times

D

16 times

Text Solution

Verified by Experts

The correct Answer is:
C
`K_(C)=[X^(+3)][Y^(-3)]` ....(1)
`K_(C)=[X^(+3)]{(1)/(2)[Y^(-)]}^(3)` ....(2)
(1)=(2)
`(1)/(8)[X^(+3)]^(1)=[X^(+3)]`
`[X^(+3)]^(1)=8[X^(+3)]`
