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/vn/v

B

n/V2n/V^{2}

C

(n/V)2(n/V)^{2}

D

1/V21/V^{2}

Answer

(n/V)2(n/V)^{2}

Explanation

Solution

For of intermolecular attraction is considered in real gas and for real gases pressure is given by

P=nRTV−nb−n2aV2.P = \frac{nRT}{V - nb} - \frac{n^{2}a}{V^{2}}. Here (nV)2\left( \frac{n}{V} \right)^{2}represents the reduction in pressure due to intermolecular attraction
