The term that corrects for the attractive forces present in a real gas in the van der Waal's equation is

Options

A. nb
B. `(an^(2))/(V^(2))`
C. `(an^(2))/(V^(2))`
D. `-nb`

Answer

B

Explanation

In the van der Waals’ equation `(p + (n^(2)a)/(V^(2))) (V-nb) = nRT`
The additional factor in pressure, i.e. `(n^(2)a)/(V^(2))` corrects for intermolecular force while b corrects for molecular volume.
