Chapter 6, Problem 6.145QP

Interpretation Introduction

Interpretation: The gas for which the effect of the volume occupied by the gas molecules is more important than the attractive forces is to be identified.

Concept introduction: At high pressure, there is a deviation in the behavior of real gases from the predictions of an ideal gas.

The van der Waals equation for ideal gas is,

$PV=n\text{R}T$

The van der Waals equation for real gas is,

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

To determine: The gas for which the effect of the volume occupied by the gas molecules is more important than the attractive forces.
