Question

Which of the following mixtures of gases does not obey Dalton’s law of partial pressure ?

• A. $O_2$ and $C{O}_2$
• B. $N_2$ and $O_2$
• C. $C{l}_2$ and $O_2$
• D. $N{H}_3$ and $HCl$

Answer 1

The correct option is D $N{H}_3$ and $HCl$

Dalton's law of partial pressure is applicable to non reacting gases. Here $N{H}_3$ and $HCl$ react to form $N{H}_{4}Cl$
So, option (d) is correct.
