Solution

The correct option is C $N H_{3} + H C l$
Daltons law of partial pressure is applicable only for non-reacting gases.
According to this law,
p = p1 + p2 + p3 +………
Where , p1, p2, p3,…. are partial pressures of components of gases.
Consider the following systems,
$O_{2} + O_{3} \to N o - r e a c t i o n .$
$C O + C O_{2} \to N o - r e a c t i o n$
$N H_{3} + H C l \to N H_{4} C l$
$I + O_{2} \to N o - r e a c t i o n .$
Hence Dalton’s law is not applicable to $N H_{3} + H C l$ .
