Chapter 7, Problem 7.6NP

Interpretation Introduction

Interpretation : The values of a, b, and V_m for the van der Waals gas should be calculated.

Concept Introduction :

Slope of compressibility factor z as a function of P and $\text{P}\to \text{0}$ is related to the Van der Waals parameters by,

  ${\left(\frac{\partial z}{\partial P}\right)}_T=\frac{1}{RT}\left(b-\frac{a}{RT}\right)$

Here, R is Universal gas constant, T is temperature and a and b are constants.
