Question

In van der Waals equation of state for a non-ideal gas, the term that accounts for intermolecular forces is :

• A. $V-b$
• B. $RT$
• C. $p+\frac{a}{V^2}$
• D. $(RT{)}^{-1}$

Answer 1

The correct option is C $p+\frac{a}{V^2}$

$[P+\frac{a{n}^2}{V^2}](V-nb)=nRT$

The above equation is called van der Waals equation,

$[p+a/V^2]$

It represents the correct for an intermolecular force of attraction. where $a$ is constant.

So, the correct option is $C$
