Vedclass · Answer

(C) The van der Waals equation is given by $\left( P + \frac{a}{V^2} \right)(V - b) = RT$. In this equation,the term $\frac{a}{V^2}$ is added to the pressure $P$ to account for the intermolecular forces of attraction between gas molecules. Thus,$a$ is a constant related to the intermolecular force of attraction. The term $b$ is subtracted from the molar volume $V$ to account for the finite volume occupied by the gas molecules themselves. Thus,$b$ is a constant related to the volume correction (excluded volume). Therefore,$a$ represents the intermolecular force of attraction and $b$ represents the volume correction.

In the van der Waals equation $\left( P + \frac{a}{V^2} \right)(V - b) = RT$,what do $a$ and $b$ represent?
