$N_{2} + 3H_{2} \rightleftharpoons 2NH_{3} + \text{heat}$. What is the effect of the increase of temperature on the equilibrium of the reaction?

The endothermic reaction $(M + N \rightleftharpoons P)$ is allowed to attain an equilibrium at $25^o C$. Formation of $P$ can be increased by

When $NaNO_3$ is heated in a closed vessel,$O_2$ is liberated and $NaNO_2$ is left behind. At equilibrium,

On the basis of the $Le \ Chatelier$ principle,explain how temperature and pressure can be adjusted to increase the yield of ammonia in the following reaction: $N_{2(g)} + 3H_{2(g)} \rightleftharpoons 2NH_{3(g)}$; $\Delta H = -92.38 \ kJ \ mol^{-1}$. What will be the effect of the addition of argon to the above reaction mixture at constant volume?

In the reaction ${A_2}_{(g)} + 4{B_2}_{(g)} \rightleftharpoons 2A{B_4}_{(g)}$ where $\Delta H < 0$,the formation of $AB_{4(g)}$ will be favoured by:

What happens when pressure is increased on the equilibrium system $Ice \rightleftharpoons Water$?
