Chapter 11.11, Problem 6E

Interpretation Introduction

Interpretation:

The value of parameters at $50°\text{C}$.

Concept Introduction:

Write the expression to obtain the temperature dependent parameters of the Wilson equation $\left({\Lambda }_{12}\right)$.

${\Lambda }_{12}=\frac{{\underset{\_}{V}}_2}{{\underset{\_}{V}}_1}\exp \left(\frac{-a_{12}/R}{T}\right)$

Here, Wilson parameter is $a_{12}/R$, liquid molar volume of component 2 is ${\underset{\_}{V}}_2$, and liquid molar volume of component 1 is ${\underset{\_}{V}}_1$.

Write the expression to obtain the temperature dependent parameters of the Wilson equation $\left({\Lambda }_{21}\right)$.

${\Lambda }_{21}=\frac{{\underset{\_}{V}}_1}{{\underset{\_}{V}}_2}\exp \left(\frac{-a_{21}/R}{T}\right)$

Here, Wilson parameter is $a_{21}/R$.
