Chapter 7.6, Problem 1E

(A)

Interpretation Introduction

Interpretation:

The van der Waals parameter $a$ and $b$ of methanol.

Concept Introduction:

The expression for van der Waals parameter $a$.

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

Here, critical temperature is $T_c$, critical pressure is $P_c$, and gas constant is $R$.

The expression for van der Waals parameter $b$.

$b=\frac{R{T}_c}{8P_c}$
