Chapter 1, Problem 1C.1AE

(i)

Interpretation Introduction

Interpretation: The pressure exerted by $\text{1}\text{mol}{\text{C}}_{\text{2}}{\text{H}}_{\text{6}}$ behaving as a van der Waals gas confined at $273.15\text{K}$ in $22.414{\text{dm}}^{\text{3}}$ has to be calculated.

Concept introduction: The van der Waals equation defines 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,

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

(ii)

Interpretation Introduction

Interpretation: The pressure exerted by $\text{1}\text{mol}{\text{C}}_{\text{2}}{\text{H}}_{\text{6}}$ behaving as a van der Waals gas confined at $1000\text{K}$ in $100{\text{cm}}^{\text{3}}$ 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,

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