Consider the equilibrium ${N_2}_{(g)} + 3{H_2}_{(g)} \rightleftharpoons 2N{H_3}_{(g)}$,$\Delta H = -93.6 \ kJ$. The maximum yield of ammonia is obtained by:

Le Chatelier's principle is applicable to:

In a reversible reaction at $300 \ K$,$K_c > K_p$ and $\Delta H = +40 \ kcal$. The product will be obtained in a higher amount on:

What will be the effect of pressure on the equilibrium reaction $C_{(s)} + H_2O_{(g)} \rightleftharpoons H_{2_{(g)}} + CO_{(g)}$?

The following reaction is known to occur in the body $CO_2 + H_2O \rightleftharpoons H_2CO_3 \rightleftharpoons H^{+} + HCO_3^-$. If $CO_2$ escapes from the system:

At $25\,^oC$,the equilibrium $SO_2Cl_2(g) \rightleftharpoons SO_2(g) + Cl_2(g)$ is established in a closed vessel. When $Cl_2$ is added to the equilibrium mixture,which of the following statements is/are correct for the system?
$(1)$ Change in concentrations of $SO_2$,$Cl_2$,and $SO_2Cl_2$.
$(2)$ More $Cl_2$ is produced.
$(3)$ The concentration of $SO_2$ decreases and the concentration of $SO_2Cl_2$ increases.
