In which of the following
reactions, the equilibrium remains unaffected on addition of small amount of
argon at constant volume?
(a) \[{{H}_{2}}(g)+{{I}_{2}}(g)\underset{{}}{\leftrightarrows}HI(g)\]
(b) \[PC{{l}_{5}}(g)\underset{{}}{\leftrightarrows}PC{{l}_{3}}(g)+C{{l}_{2}}(g)\]
(c) \[{{N}_{2}}(g)3{{H}_{2}}(g)\underset{{}}{\leftrightarrows}2N{{H}_{3}}(g)\]
(d) The equilibrium will remain
unaffected in all the three cases.
Answer:
(d) At constant volume, there is
no effect of inert gas addition.
