Question:
In which of the following reactions, the equilibrium remains unaffected on
addition of small amount of argon at constant volume?
(i) H2 (g) + I2 (g) ⇌ 2HI (g)
(ii)PCl5 (g) ⇌ PCl3 (g) + Cl2 (g)
(iii) N2 (g) + 3H2 (g) ⇌ 2NH3 (g)
(iv) The equilibrium will remain unaffected in all the three cases.
Solution:
Option (iv) The equilibrium will remain unaffected in all the three cases. is the answer.
