Q. If the volume of the gas containing $n$ number of molecules is $V,$ then the pressure will decrease due to force of intermolecular attraction in the proportion
A) $n/V$
B) $n/V^{2}$
C) $(n/V)^{2}$
D) $1/V^{2}$
Explanation
(c) For intermolecular attraction is considered in real gas and for real gases pressure is given by
$P = \frac{nRT}{V - nb} - \frac{n^{2}a}{V^{2}}.\ Here\ \left( \frac{n}{V} \right)^{2}$ represents the reduction in pressure due to intermolecular attraction
