The molar concentration of $\mathrm{A}$ and $\mathrm{B}$ are $0.80 \mathrm{mol} {\mathrm{L}}^{-1}$. On mixing them, the reaction starts to proceed as $\mathrm{A}+\mathrm{B}\stackrel{ }{\rightleftharpoons }\mathrm{C}+\mathrm{D}$ and attain equilibrium. At equilibrium molar concentration of $\mathrm{C}$ is $0.60 \mathrm{mol} {\mathrm{L}}^{-}$. Calculate ${\mathrm{K}}_{\mathrm{c}}$ of the reaction.

A mixture of $3$ moles of ${\mathrm{H}}_2$ and $1$ mole of ${\mathrm{N}}_2$ react at constant pressure of $100 \mathrm{atm}$. At equilibrium $0.5$mole of ammonia is formed. Calculate the value ${\mathrm{K}}_{\mathrm{p}}$ for the equilibrium reaction $\frac{3}{2}{\mathrm{H}}_2+\frac{1}{2}{\mathrm{N}}_2\stackrel{ }{\rightleftharpoons }{\mathrm{NH}}_3$.

The value of ${\mathrm{K}}_{\mathrm{p}}$ for dissociation of $2\mathrm{HI}\underset{}{\overset{ }{\rightleftharpoons }}{\mathrm{H}}_2+{\mathrm{I}}_2$ is $1.84\times {10}^{-2}$. If the equilibrium concentration of ${\mathrm{H}}_2$ is $0.4789 \mathrm{mol} {\mathrm{L}}^{-1}$. Calculate the concentration of $\mathrm{HI}$ at equilibrium.

${\mathrm{K}}_{\mathrm{sp}}$ of $\mathrm{AgCl}$ is $2.8\times {10}^{-10}$ at ${25}^{°} \mathrm{C}$. Calculate solubility of $\mathrm{AgCl}$ in pure water.
