Question

Cosider the reactions
$i\left)PC{l}_5\right(g)\rightleftharpoons PC{l}_3(g)+C{l}_2(g).$
$ii\left)N_2{O}_2\right(g)\rightleftharpoons 2N{O}_2(g).$
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 distrub the equilibrium of the reactions

Answer 1

Answer: (D)

will not distrub the equilibrium of the reactions

The addition of the inert gas at constant volume, has no effect on the equilibrium of the reaction. This is because, the number of moles of reactants and products are same.
