Chapter 6, Problem 6.141QP

Interpretation Introduction

Interpretation: The rearrangement of the van der Waals equation for pressure is to be solved and the pressure exerted by a real gas lower than the pressure for an ideal gas at the same temperature and volume is to be stated.

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

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

Here, $\text{a}$ is the pressure correction factor.

To determine: The rearrangement of the van der Waals equation for pressure and the pressure exerted by a real gas lower than the pressure for an ideal gas at the same temperature and volume.
