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 :-

Options

A. 2 times
B. 4 times
C. 8 times
D. 16 times

Answer

C

Explanation

`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)]`
