NEET levelSingle correct optionDifficulty 1 of 3rg012

In the van der Waals equation $(P + \frac{a n ^{2}}{V ^{2}}) (V - nb) = n RT$ , the term $\frac{a n ^{2}}{V ^{2}}$ corrects for

Athe finite size of molecules
Bthe attractive forces between molecules
Cthe kinetic energy of molecules
Dthe rotational motion of molecules

Answer: B

The pressure correction

a n^{2} / V^{2}

is added because attractions pull molecules inward and lower the observed pressure below the ideal value. The volume correction

nb

accounts for finite molecular size.
