Chapter 1, Problem 1C.9BE

Interpretation Introduction

Interpretation: The van der Waals constant, $b$ and the compressibility factor for the gas at the prevailing temperature and pressure has to be calculated.

Concept introduction: The van der Waals equation defined the behavior of real gases.  This includes the forces of attraction and repulsion in the real gases.  This is represented by the formula given below as,

  $p=\frac{nRT}{V-nb}-a{\left(\frac{n}{V}\right)}^2$

The compression factor is defined as the ratio of molar volume of a gas to the molar volume of a perfect gas.  This is represented by the formula given below as,

  $Z=\frac{V_{\text{m}}}{V_{\text{m}}^{\text{°}}}$
