Question

In a vessel, $\mathrm{N}_2, \mathrm{H}_2$ and $\mathrm{NH}_3$ are at equilibrium. Some helium gas is introduced into the vessel so that total pressure increases while temperature and volume remain constant. According to Le Chatelier's principle, the dissociation of $\mathrm{NH}_3$

Professor PC Thomas Classes · Answer

(c) : If the volume is kept constant and an inert gas is added that does not take part in the reaction, the equilibrium remains undisturbed.
