Question

In which of the following reactions, the equilibrium remains unaffected on addition of small amount of argon at constant volume?

• A. $H_{2(g)} + I_{2(g)}$ $2HI_{(g)}$
• B. $PCl_{5(g)}$ $PCl_{3(g)} + Cl_{2(g)}$
• C. $N_{2(g)} + 3H_{2(g)}$ $2NH_{3(g)}$
• D. The equilibrium will remain unaffected in all the three cases.

Answer 1

Answer: (D)

The equilibrium will remain unaffected in all the three cases.

Answer 2

: If the volume is kept constant and an inert gas such as argon is added which does not take part in the reaction, the equilibrium remains undisturbed.
