$\mathrm{PbCl}_{2(\mathrm{s})} \rightleftharpoons \mathrm{Pb}_{(\mathrm{ag})}^{2+}+2 \mathrm{Cl}_{(\mathrm{aq})}^{-}$
Which of the following choices is correct for a mixture of $300\; \mathrm{mL}\;\; 0.134 \;\mathrm{M} \;\mathrm{Pb}\left(\mathrm{NO}_{3}\right)_{2}$ and $100\; \mathrm{mL}\;\; 0.4\; \mathrm{M}\; \mathrm{NaCl} ?$
$4C{a_5}{(P{O_4})_3}F + 18Si{O_2} + 30C \to 3{P_4} + 2Ca{F_2} + 18CaSi{O_3} + 30CO$
$X \rightleftharpoons Y + Z$ $...(i)$
$A \rightleftharpoons 2B$ $...(ii)$
are in the ratio $9 : 1.$ If degree of dissociation of $X$ and $A$ be equal, then total pressure at equilibrium $(i)$ and $(ii)$ are in the ratio
