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. `(n^(2)a)/V^(2)`
C. `-((n^(2)a)/(V^(2)))`
D. `-nb`

Answer

B

Explanation

In the van der Waals' equation
`(p+(n^(2)a)/(V^(2)))(V-nb)=nRT`
The pressure correction factor `(n^(2)a//V^(2))` accounts for intermolecular attraction in real gas.
