Q. In which of the following reactions, the equilibrium remains unaffected on addition of small amount of argon at constant volume?
Equilibrium
A
$H _2( g )+ I _2( g ) \rightleftharpoons 2 HI _{ g )}$
36%
B
$PCl _5( g ) \rightleftharpoons PCl _{3( g )}+ Cl _2( g )$
14%
C
$N _2( g )+3 H _2( g ) \rightleftharpoons 2 NH _3( g )$
7%
D
The equilibrium will remain unaffected in all the three cases
43%
Solution:
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.
