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

A

nb

B

`(an^(2))/(V^(2))`

C

`(an^(2))/(V^(2))`

D

`-nb`

Text Solution

Verified by Experts

The correct Answer is:
B
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.
