Chapter 8.5, Problem 5E

(A)

Interpretation Introduction

Interpretation:

The fugacity of propane.

Concept Introduction:

The equation for the van der Waals parameter $\left(a\right)$ is,

$a=\frac{27R^2{T}_c^2}{64P_c}$

Here, gas constant is $R$, critical temperature and critical pressure is $T_c\text{and}{P}_c$ respectively.

The expression for fugacity $\left(f\right)$ is,

$\ln \frac{f}{P}={\displaystyle \underset{P=0}{\overset{P=P}{\int }}\frac{Z-1}{P}dP}$

Here, compressibility factor is Z, pressure is P, and change in pressure is $dP$.

Interpretation Introduction

Interpretation:

The fugacity of propane.

(C)

Interpretation Introduction

Interpretation:

The fugacity of propane.

Concept Introduction:

The expression of fugacity is,

$\ln \left(\frac{f}{P}\right)={\displaystyle {\int }_{T=T,P=0}^{T=T,P=P}\left[\frac{Z-1}{P}\right]}dP$

(D)

Interpretation Introduction

Interpretation:

The fugacity of propane.
