The Antoine Equation is an empirical relationship commonly used to compute the vapor pressure, of different components.
where is given in kPa and is given in The parameters for benzene are
The vapor pressure can also be computed using the generalized PengRobinson equation of state. Properties of benzene can be obtained from Table
a Using the generalized PengRobinson equation of state and the critical parameters for benzene, generate plots of vs for and Using these graphs, what is the approximate location of the critical temperature? Explain your choice. Be sure to label your axis with appropriate units
Hints:
The internet is your friend. If you're not familiar with these python commands look them up
You will want to plot your axis on a scale. The numpy logspace function is useful for evenly spacing points in log space. You can change your axis to be on a log axis using matplotlib.pyplot.xscalelog
The pressure predicted by the PR EOS explodes approaches infinity as Furthermore, the PR EOS is invalid for careful with the range A reasonable starting guess generate your values though you might need tweak these ranges throughout this question.
Python functions and for loops are your friend. Use them!
