Question

Consider the reactions
(i) $PC{l}_5\left(g\right)\rightleftharpoons PC{l}_3\left(g\right)+C{l}_2\left(g\right)$
(ii) $N_2{O}_4\left(g\right)\rightleftharpoons 2N{O}_2\left(g\right)$
The addition of an inert gas at constant volume:

• A. will increase the dissociation of $PC{l}_5$ as well as $N_2{O}_4$
• B. will reduce the dissociation of $PC{l}_5$ as well as $N_2{O}_4$
• C. will increase the dissociation of $PC{l}_5$ and step up the formation of $N{O}_2$
• D. will not disturb the equilibrium of the reactions

Answer 1

The correct option is D will not disturb the equilibrium of the reactions

If the inert gas is added to each given reactions at constant volume then equilibrium of reactions will not to disturbed because insert gases do not react with any of the reactant or product species to affect the reaction equilibrium.
