Question

If $V$ is the volume of one molecule of a gas under given conditions then, van der Waals constant $b$ is:

• A. $4V$
• B. $\frac{4V}{N_0}$
• C. $N_0/4V$
• D. $4VNo$

Answer 1

The correct option is A $4V$

$\text{Vanderval's Equation:}(P+\frac{a{n}^2}{V^2})(V-nb)=nRT\Rightarrow \text{Vanderval's Constant in terms of Volume of the molecule}\Rightarrow b=4V$
