Chapter 6, Problem 6.140QP

Interpretation Introduction

Interpretation: An explanation corresponding to the fact that the constant $a$ in the van der Waals equation generally increases with the molar mass of the gas is to be stated.

Concept introduction: The van der Waals equation for the real gases is,

$\left(P+\frac{n^2\text{a}}{V^2}\right)\left(V-n\text{b}\right)=n\text{R}T$

To determine: An explanation corresponding to the fact that the constant $a$ in the van der Waals equation generally increases with the molar mass of the gas.
