    If the volume of the gas containing m number of molecules is V, then the pressure will decrease due to force of intermolecular attraction in the proporation.

    A)  \[n/V\]                               

    B)  \[n/{{V}^{2}}\]

    C) \[~{{(n/V)}^{2}}\]                           

    D) \[1/{{V}^{2}}\]

    Correct Answer: C

    Solution :

    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 presence due to intermolecular attraction.
