Question

For which of the following mixture of gases, Dalton's law of partial pressure is not applicable at room temperature?

• A. $HCl+N{H}_3$
• B. $CO+C{O}_2$
• C. $O_2+N_2$
• D. $S{O}_2+O_2$

Answer 1

Answer: (A)

$HCl+N{H}_3$

Dalton's law of partial pressure is not applicable at room temperature for a mixture of reacting gases.

Thus, Dalton's law of partial pressure is not applicable at room temperature for a mixture of (A) hydrogen chloride and ammonia.

Hence, the correct answer is option $\text{A}$.
