Chapter 6, Problem 122IAE

Interpretation Introduction

(a)

Interpretation:

The pressure of one mole of of O₂(g) and percent error in the calculated pressure should be determined.

Concept introduction:

Van der Waals equation is:

$\begin{array}{l}\left(\text{P+}\frac{{\text{an}}^{\text{2}}}{{\text{V}}^{\text{2}}}\right)\left(\text{V-nb}\right)\text{ = nRT}\\ \text{P = pressure}\\ \text{V = volume}\\ \text{T = temperature}\\ \text{R = universal gas constant }\\ \text{n = number of moles}\\ \text{a and b = van der Waals constants}\end{array}$

Interpretation Introduction

(b)

Interpretation:

The volume of one mole of O₂ and percent error in the calculated volume should be determined.

Concept introduction:

The ideal gas equation is,

$PV=nRT$

Where pressure is represented by P, number of mole is represented by n, volume is represented by V, universal gas constant is represented by R, and temperature is represented by T.
