The term that corrects for the attractive forces present in a real gas in the van der Waals' equation is
The term that corrects for the attractive forces present in a real gas in the van der Waals' equation is
$n b$
$n^2 a / V^2$
$-\left(n^2 a / V^2\right)$
$-n b$
Solution
In the van der Waals' equation
$
\left(p+\frac{n^2 a}{V^2}\right)(V-n b)=n R T
$
The pressure correction factor $\left(n^2 a / V^2\right)$ accounts for intermolecular attraction in real gas
