Question

For the reaction $PC{l}_5\left(g\right)\rightleftharpoons PC{l}_3\left(g\right)+C{l}_2\left(g\right)$ The forward reaction at constant temperature is favoured by :

• A. Introducing an inert gas at constant volume
• B. Introducing chlorine gas at constant volume
• C. Introducing an inert gas at constant pressure
• D. Increasing the volume of the container
• E. Introducing $PC{l}_5$, at constant volume

Answer 1

Answer: (C), (D), (E)

The correct options are
C Introducing an inert gas at constant pressure
D Increasing the volume of the container
E Introducing $PC{l}_5$, at constant volume

At constant volume, there is no effect of addition of inert gas to a reaction in equilibrium.

At constant pressure, for the reactions for which Δn=0Δn=0, Hence, option C, D and E are correct by using the above discussion based on Le, Chatllier's principle
