Chapter 5, Problem 9RQ

Interpretation Introduction

Interpretation: The reason for the addition of term to observed pressure and subtraction from container volume to correct for non-ideal gas behavior.

Concept Introduction:

The Vander’s Waal equation can be written as,

$\left[{\text{P}}_{\text{obs}}\text{+a}{\left(\frac{\text{n}}{\text{V}}\right)}^{\text{2}}\right]\text{×(V-nb)=nRT}$

The first term is the corrected pressure called as pressure ideal and the second term is the corrected volume called as volume ideal.
