| Column $I$ | Column $II$ |
| $(A)$ $\mathrm{Bi}^{3+} \longrightarrow(\mathrm{BiO})^{+}$ | $(P)$ Heat |
| $(B)$ $\left[\mathrm{AlO}_2\right]^{-} \longrightarrow \mathrm{Al}(\mathrm{OH})_3$ | $(Q)$ Hydrolysis |
| $(C)$ $\mathrm{SiO}_4^{4-} \longrightarrow \mathrm{Si}_2 \mathrm{O}_7^{6-}$ | $(R)$ Acidification |
| $(D)$ $\left(\mathrm{B}_4 \mathrm{O}_7^{2-}\right) \longrightarrow\left[\mathrm{B}(\mathrm{OH})_3\right]$ | $(S)$ Dilution by water |
$X \rightleftharpoons Y + Z - - - - - - \left( 1 \right)$
$A \rightleftharpoons 2B - - - - - - \left( 2 \right)$
are in ratio of $9 :1$. If degree of dissociation of $X$ and $A$ be equal, then total pressure at equilibrium $(1)$ and $(2)$ are in the ratio
