For the equilibrium process $H_2O_{(l)} \rightleftharpoons H_2O_{(g)}$,what happens if the pressure is increased?

Which of the following conditions is favorable for the forward reaction in the equilibrium: $H_2 \rightleftharpoons H + H$ $(\Delta H = +ve)$?

The formation of ammonia from its constituent elements is an exothermic reaction. The effect of increasing temperature on the reaction equilibrium is

For the equilibrium $2NO_{2(g)} \rightleftharpoons N_2O_{4(g)} + 21.9 \ kcal$,an increase in temperature will:

Two systems $PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)}$ and $COCl_{2(g)} \rightleftharpoons CO_{(g)} + Cl_{2(g)}$ are in equilibrium simultaneously in a container of constant volume. If some $CO_{(g)}$ is added to the container at constant volume,then at the new equilibrium:

Which of the following changes will shift the reaction towards the product?
$I_{2(g)} \rightleftharpoons 2I_{(g)}$ $\Delta H_r^o(298 \ K) = +150 \ kJ$
