What happens when a saturated solution of $CO_2$ is heated?

The exothermic formation of $ClF_3$ is represented by the equation $Cl_{2(g)} + 3F_{2(g)} \rightleftharpoons 2ClF_{3(g)}$; $\Delta H = -329 \ kJ$. Which of the following will increase the quantity of $ClF_3$ in an equilibrium mixture of $Cl_2, F_2$ and $ClF_3$?

What would happen to a reversible reaction at equilibrium when an inert gas is added while the pressure remains unchanged?

For the equilibrium reaction $2NO \rightleftharpoons N_2 + O_2 + x \, cal$,which condition is suitable for the greater dissociation of $NO$?

The effect of the addition of helium gas to the following reaction in an equilibrium state is:
$PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)}$

According to Le Chatelier's principle,an increase in the temperature of the following reaction will:
$N_2 + O_2 \rightleftharpoons 2NO - 43,200 \ kcal$
