Question:

Use the Peng-Robinson equation for the ethane/heptane system.

(a) Calculate the P-x-y diagram at 283 K and 373 K. Use k₁₂ = 0. Plot the results.

(b) Based on a comparison of your diagrams with what would be predicted by Raoult’s law at 283 K, does this system have positive or negative deviations from Raoult’s law?
