Question

Which of the following gas mixture is not applicable for Dalton’s law of partial pressure.

• A. $V \propto \frac{1}{T}$ and $PV = RT$
• B. $V \propto 1/P$ and $PV = nRT$
• C. $cm^{3}$ and $cm^{3}$
• D. $20 \times \frac{1}{50}$ and $50 \times \frac{1}{20}$

Answer 1

Answer: (A)

$V \propto \frac{1}{T}$ and $PV = RT$

Answer 2

Mixture of $Z = \frac{pV_{m}}{RT} = 1 - \frac{a}{RT}$and $\left( p + \frac{a}{V_{m}^{2}} \right)(V_{m}) = RT$ are reacted chemically and forms $pV_{m} = RT$. That is why mixture of these gases is not applicable for Dalton's law.
