Chapter 7, Problem 7.18NP

Interpretation Introduction

Interpretation : The Redlich-Kwong parameters of fluorine should be calculated from the values of the critical constants.

Concept Introduction :

The correction for intermolecular forces can be represented as follows:

  $a=\frac{R^2{T}_c{}^{5/2}}{9P_c\left(2^{1/3}-1\right)}$

Here,

a − correction for intermolecular forces

R − Universal gas constant

T_c − critical temperature

P_c − critical pressure

  $b=\frac{\left(2^{1/3}-1\right)R{T}_c}{3P_c}$

Here,

b − correction for volume
