Chapter 2, Problem 2.24NP

Interpretation Introduction

Interpretation: The value for $\text{w}$ needs to be calculated for a sample a gas under given conditions assuming that the gas is described by the ideal gas law.

Concept Introduction: For ideal gas, the relation between $\text{n}$ number of moles of gas under pressure, $\text{P}$ , volume, $\text{V}$ at temperature, $\text{T}$ is given as:

  $\text{PV = nRT}$ - (1)

Where $\text{R}$ is universal gas constant.

Interpretation Introduction

Interpretation: The value for $\text{w}$ needs to be calculated for a sample a gas under given conditions assuming that the gas is described by the van der Waals equation. Also, the percent error needs to be determine for using ideal gas law instead of van der Waals equation.

Concept Introduction: For van der Waals equation, the relation between $\text{n}$ number of moles of gas under pressure, $\text{P}$ , volume, $\text{V}$ at temperature, $\text{T}$ is given as:

  $\text{P = }\frac{\text{nRT}}{\text{V - nb}}-\frac{{\text{n}}^2\text{a}}{{\text{V}}^2}$

Where $\text{R}$ is universal gas constant, a andb are van der Waals constant.
