For a reaction,the value of $K_p$ increases with an increase in temperature. The $\Delta H$ for the reaction would be

The reaction,$N_{2(g)} + 3H_{2(g)} \rightleftharpoons 2NH_{3(g)}$ is exothermic and reversible. $A$ mixture of $N_{2(g)}$,$H_{2(g)}$,and $NH_{3(g)}$ is at equilibrium in a closed container. When a certain quantity of extra $H_{2(g)}$ is introduced into the container,while keeping the volume constant,then which statement among the following is true?

The equilibrium of the reaction $2A_{(s)} + 3B_{(g)} \rightleftharpoons 3C_{(g)} + D_{(g)} + Q$ is represented as shown. If the pressure on the system is reduced to half of its original value,then:

In a reversible reaction,$K_c > K_p$ and $\Delta H = +40 \, kcal$. The formation of product will be less at:

Le Chatelier's principle is applicable only to a

$N_2 + O_2 \rightleftharpoons 2NO - Q \, cal$. In the above reaction,which is the essential condition for the higher production of $NO$?
