$H_{2(g)} + I_{2(g)} \rightleftharpoons 2HI_{(g)}$. In this reaction,when pressure increases,the reaction direction:

When in any system at equilibrium state,pressure,temperature,and concentration are changed,then the equilibrium shifts in such a direction as to neutralize the effect of the change. This is known as:

Which of the following is not favourable for $SO_3$ formation in the reaction $2SO_{2(g)} + O_{2(g)} \rightleftharpoons 2SO_{3(g)}; \Delta H = -45.0 \ kcal$?

In the reaction: $H_2S \rightleftharpoons 2H^{+} + S^{2-}$,when $NH_4OH$ is added,then

When a sample of $NO_2$ is placed in a container,this equilibrium is rapidly established: $2NO_{2(g)} \rightleftharpoons N_2O_{4(g)}$. If this equilibrium mixture is a darker colour at high temperatures and at low pressure,which of these statements about the reaction is true?

What happens when an inert gas is added at constant pressure to a reversible decomposition reaction that is in equilibrium?
