Seema Saini Solutions for Chapter: Chemical Equilibrium, Exercise 3: DPP 6.3

Some quantity of water is contained in a container as shown as shown in figure. As neon is added to this system at constant pressure, the amount of liquid water in the vessel

The equilibrium $2{\mathrm{Cu}}^1\rightleftharpoons {\mathrm{Cu}}^0+{\mathrm{Cu}}^{\mathrm{II}}$ in aqueous medium at $25 °\mathrm{C}$ shifts towards the left in the presence of which of the following?

The thermal dissociation equilibrium reaction of ${\mathrm{CaCO}}_3 \left(\mathrm{s}\right)$ is studied under different conditions
${\mathrm{CaCO}}_3 \left(\mathrm{s}\right)\rightleftharpoons \mathrm{CaO} \left(\mathrm{s}\right)+{\mathrm{CO}}_2 \left(\mathrm{g}\right)$

For this equilibrium reaction, the correct statement(s) is/ (are):

When ${\mathrm{NaNO}}_3$ is heated in a closed vessel, oxygen is liberated and ${\mathrm{NaNO}}_2$ is left behind. At equilibrium ${\mathrm{NaNO}}_3 \left(\mathrm{s}\right)\rightleftharpoons {\mathrm{NaNO}}_2 \left(\mathrm{s}\right)+\frac{1}{2}{\mathrm{O}}_{2 }\left(\mathrm{g}\right)$,

An industrial fuel, 'water gas', which consists of a mixture of ${\mathrm{H}}_2$ and $\mathrm{CO}$ can be made by passing steam over red-hot carbon. The reaction is
$\mathrm{C}\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)\rightleftharpoons \mathrm{CO}\left(\mathrm{g}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right), \mathrm{\Delta H}=+131 \mathrm{kJ}$
The yield of $\mathrm{CO}$ and ${\mathrm{H}}_2$ at equilibrium would be shifted to the product side by:

The reactions in which the yield of the products cannot be increased by applying high pressure are

For the reaction: ${\mathrm{PCl}}_5\left(\mathrm{g}\right)\rightleftharpoons {\mathrm{PCl}}_3\left(\mathrm{g}\right)+{\mathrm{Cl}}_2\left(\mathrm{g}\right)$
The forward reaction at constant temperature is favoured by

For the reaction,
$2\mathrm{A} \left(\mathrm{g}\right)+\mathrm{B} \left(\mathrm{g}\right)\rightleftharpoons 2\mathrm{C} \left(\mathrm{g}\right), \mathrm{\Delta H}=+13.6 \mathrm{kJ}$, which of the following will increase the extent of the reaction at equilibrium?
