CALCULATING FUGACITY

COEFFICIENTS BY INTEGRATING AN

EOS

Using the van der Waals equation:

$P=\frac{RT}{(\frac{?}{\text{b}\text{a}\text{r}}(\frac{?}{\text{b}\text{a}\text{r}}(V))-b)}-\frac{a}{\frac{?}{\text{b}\text{a}\text{r}}(V{)}^2}$

$ln={\displaystyle \underset{0}{\overset{P}{}}}(\frac{(\frac{?}{\text{b}\text{a}\text{r}}(V))}{RT}-\frac{1}{P})delP$

$ln=ln(\frac{\frac{?}{\text{b}\text{a}\text{r}}(\frac{?}{\text{b}\text{a}\text{r}}(V))}{\frac{?}{\text{b}\text{a}\text{r}}(\frac{?}{\text{b}\text{a}\text{r}}(V))-b})+\frac{b}{\frac{?}{\text{b}\text{a}\text{r}}(\frac{?}{\text{b}\text{a}\text{r}}(V))-b}-\frac{2a}{\frac{?}{\text{b}\text{a}\text{r}}(\frac{?}{\text{b}\text{a}\text{r}}(V))RT}-ln\frac{P(\frac{?}{\text{b}\text{a}\text{r}}(V))}{RT}$
