Question

The term that corrects for the attractive forces present in a real gas in the Van der Waals equation is _____.

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

From Van der Waals equation,

$⟮P_{measured}+\frac{a{n}^2}{v^2}⟯⟮V-nb⟯=nRT$

$P_{ideal}=P_{measured}+\frac{a{n}^2}{v^2}$

$\Rightarrow \frac{a{n}^2}{v^2}$ is the correction term.
