Question $1_{?}$

Ethylene at $167C$ and $7$ bar is being processed, and the following virial coefficients were reported:

$B=-54\mathrm{.}8c\frac{m^3}{m}ol,C=4120c\frac{m^6}{m}o{l}^2$

Estimate the molar volume and the compressiblity factor for ethylene under these conditions by the:

a$)$ Ideal gas equation.

b$)$ The virial equation of state truncated to second virial coefficient.

c$)$ The virial equation of state truncaled to third virial coefficient.

Question $2$

Determine the molar volume and compressibility factor for o$-$xylene at $650K$ and $35$ bar assuming that the compound is a:

a$)$ Van der Waals fluid.

b$)$ Peng$-$Robinson fluid. $($Homework$)$

c$)$ Redlich$-$Kinong fluid. $($Homework$)$

d$)$ Soave$-$Redlich$-$Kwong fluid. $($Homework$)$
