Which of the following can be explained by Le Chatelier's principle?

$A$ container at equilibrium contains $SO_3, SO_2$ and $O_2$. The total pressure in the container is increased while the temperature and volume remain constant. According to Le Chatelier's principle,the dissociation of $SO_3$ will........

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

In which of the following equilibria does a change in the volume of the system not alter the number of moles?

For the reaction $N_{2(g)} + 3H_{2(g)} \rightleftharpoons 2NH_{3(g)} + 21.9 \ kcal$,which conditions favor the production of ammonia?

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:
