Question

For the non-zero values of force of attraction between gas molecules, gas equation will be :

• A. PV = nRT - $\frac{-n^{2}a}{V}$
• B. PV = nRT + nBP
• C. PV = nRT
• D. P = $\frac{nRT}{V-b}$

Answer 1

The correct option is A PV = nRT - $\frac{-n^{2}a}{V}$

For the non-zero values of force of attraction between gas molecules, gas equation will be PV = nRT - $\frac{-n^{2}a}{V}$
The vander waals equation is $(P+\frac{a{n}^2}{V^2})V=nRT$
$PV+\frac{a{n}^2}{V}=nRT$
Hence, PV = nRT - $\frac{-n^{2}a}{V}$
