Question $1$

In class, we have already solved the molar volume of saturated vapor n$-$butane

at $350K$ and a vapor pressure of $9\mathrm{.}4573$ bar using the Redlich$-$Kwong equation.

Your task is to expand on this by solving for the molar volumes for vapor and

liquid using the following equations of state:

Van der Waals Equation

Soave$-$Redlich$-$Kwong $($SRK$)$ Equation

Peng$-$Robinson $($PR$)$ Equation
