Compare the Peng-Robinson vapor pressures to the experimental vapor pressures (represented by the Antoine constants) for the species listed in problem 9.13.

Data from problem 9.13

Compare the Antoine and shortcut vapor-pressure equations for temperatures from 298 K to 500 K. (Note in your solution where the equations are extrapolated.) For the comparison, use a plot of log₁₀P^sat versus 1/T except provide a separate plot of P^sat versus T for vapor pressures less than 0.1 MPa.

(a) n-Hexane

(b) Acetone

(c) Methanol

(d) 2-propanol

(e) Water
