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 timesB. 4 timesC. 8 timesD. 16 times |

Answer» Correct Answer - 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)]` |
