For the hypothetical reactions, the equilibrium constant $\left(\mathrm{K}\right)$ values are given:
$$\begin{gathered} \mathrm{A}\rightleftharpoons \mathrm{B}; {\mathrm{K}}_1 =2.0 \\ \mathrm{B}\rightleftharpoons \mathrm{C}; {\mathrm{K}}_2 =4.0 \\ \mathrm{C}\rightleftharpoons \mathrm{D}; {\mathrm{K}}_3 =3.0 \end{gathered}$$
The equilibrium constant $\left(\mathrm{K}\right)$ for the reaction $\mathrm{A}\rightleftharpoons \mathrm{D}$ is

For the reaction ${\mathrm{N}}_{2\left(\mathrm{g}\right)}+3{\mathrm{H}}_{2\left(\mathrm{g}\right)}\rightleftharpoons 2{\mathrm{NH}}_{3\left(\mathrm{g}\right)}$ at $400\mathrm{K}$, ${\mathrm{K}}_{\mathrm{p}}=41$. Find the value of ${\mathrm{K}}_{\mathrm{p}}$ for the following reaction: $\frac{1}{2}{\mathrm{N}}_{2\left(\mathrm{g}\right)}+\frac{3}{2}{\mathrm{H}}_{2\left(\mathrm{g}\right)}\rightleftharpoons {\mathrm{NH}}_{3\left(\mathrm{g}\right)}$

${\mathrm{K}}_{\mathrm{p}}$ for the following reaction will be equal to

$3{\mathrm{Fe}}_{\left(\mathrm{s}\right)}+4{\mathrm{H}}_2{\mathrm{O}}_{\left(\mathrm{g}\right)}\rightleftharpoons {\mathrm{Fe}}_3{\mathrm{O}}_{4\left(\mathrm{s}\right)}+4{\mathrm{H}}_{2\left(\mathrm{g}\right)}$

A quantity of ${\mathrm{PCl}}_5$ was heated in a $10 \mathrm{litres}$ vessel at $250°\mathrm{C}$: ${\mathrm{PCl}}_{5\left(\mathrm{g}\right)}\rightleftharpoons {\mathrm{PCl}}_{3\left(\mathrm{g}\right)}+{{\mathrm{Cl}}_2}_{\left(\mathrm{g}\right)}$. At equilibrium, the vessel contains $0.1 \mathrm{mole}$ of ${\mathrm{PCl}}_5$, $0.20 \mathrm{mole}$ of ${\mathrm{PCl}}_3$ and $0.2 \mathrm{mole}$ of ${\mathrm{Cl}}_2$. The equilibrium constant of the reaction is

In what manner will increase of pressure affect the following equilibrium? ${\mathrm{C}}_{\left(\mathrm{s}\right)}+{\mathrm{H}}_2{\mathrm{O}}_{\left(\mathrm{g}\right)}\rightleftharpoons {\mathrm{CO}}_{\left(\mathrm{g}\right)}+{\mathrm{H}}_2{\mathrm{O}}_{\left(\mathrm{g}\right)}$

Exothermic reactions are favoured by _____ temperature.

If pressure is applied on the ice $\rightleftharpoons$ water equilibrium, more of _____ will be formed.
