Chapter 8, Problem 72QRT

(a)

Interpretation Introduction

Interpretation:

Gas having highest van der Waals constant a should be predicted from $Ne,{\text{ N}}_2,\text{}{\text{H}}_{2}O{\text{ and CH}}_4.$

Concept Introduction:

Van der Waal’s gas equation:

The van der Waal equation describes the ideal gas as it approaches to zero. The van der Waal equation contains correction terms a and b for the intermolecular forces and molecular size respectively.

The van der Waal equation is as follows,

  $\left[P+a{\left(\frac{n}{V}\right)}^2\right]\left(\frac{V}{n}-b\right)=RT$

(b)
