Chemical Equilibrium

For which of the following solids does solubility decrease with an increase in temperature?

The compounds $A$ and $B$ are mixed in equimolar proportion to form the products, $A+B \rightleftharpoons C+D$. At equilibrium, one-third of $A$ and $B$ are consume(d) The equilibrium constant for the reaction is

$A+B \rightleftharpoons C+D$ The initial concentrations of $A$ and $B$ are equal. At equilibrium, the concentration of $C$ is twice that of $A$. The equilibrium constant of the reaction is

$56 \mathrm{~g}$ of nitrogen and $8 \mathrm{~g}$ of hydrogen gas are heated in a closed vessel. At equilibrium $34 \mathrm{~g}$ of ammonia are present. The equilibrium number of moles of nitrogen, hydrogen and ammonia…

For a given exothermic reaction $K_{p}$ and $K'_{p}$ are the equilibrium constants at temperatures $T_{1}$ and $T_{2}$ respectively (T2.>T1). Assuming that heat of reaction is constant in temperatures range between…

The equilibrium constants of the following are: $\begin{matrix} N_{2}+3H_{2}\rightleftharpoons\,2\mathrm{NH}_{3} & K_{1} \\ N_{2}+O_{2}\rightleftharpoons\,2\mathrm{NO} & K_{2} \\…

(i) $\mathrm{H}_3 \mathrm{PO}_4(a q) \rightleftharpoons \mathrm{H}^{+}(a q)+\mathrm{H}_2 \mathrm{PO}_4^{-}(a q)$ (ii) $\mathrm{H}_2 \mathrm{PO}_4^{-}(a q) \rightleftharpoons \mathrm{H}^{+}(a q)+\mathrm{HPO}_4^{2-}(a q)$…

$\mathrm{K}_{\mathrm{c}}$ for the reaction, $\mathrm{A}_2(\mathrm{~g}) \stackrel{\mathrm{T}(\mathrm{K})}{\rightleftarrows} \mathrm{B}_2(\mathrm{~g})$ is 99.0 . In a 1 L closed flask two moles of…

One mole of $\mathrm{PCl}_5(\mathrm{~g})$ was heated in a $1 \mathrm{~L}$ closed flask at $500 \mathrm{~K}$. At equilibrium, 0.1 mole of $\mathrm{Cl}_2(\mathrm{~g})$ was formed. What is its $\mathrm{K}_{\mathrm{p}}$ (in…

$\mathrm{K}_{\mathrm{c}}$ for the reaction $\mathrm{A}_2(\mathrm{~g}) \stackrel{\mathrm{T}(\mathrm{~K})}{\rightleftharpoons} \mathrm{B}_2(\mathrm{~g})$ is 39.0. In a closed one litre flask, one mole of…

At $\mathrm{T}(\mathrm{K}), \mathrm{K}_{\mathrm{c}}$ for the reaction. $\mathrm{A}_2(\mathrm{~g}) \rightleftharpoons \mathrm{B}_2(\mathrm{~g})$ is 99.0 . Two moles of $A_2(\mathrm{~g})$ was heated to $T(K)$ in a $1 L$…

When the reaction $A+2 B \rightleftharpoons 2 C+D$ was studied, it was observed that the initial concentration of $B$ was 1.5 times that of $A$, and the equilibrium concentrations of $A$ and $C$ were equal. Then $K_C$…
