Question:

Predict the Pxy behavior for a mixture of acetone (1) + 2-propanol (2) at 328.15 K using the Peng-Robinson equation of state. Compare the predictions to the experimental data given in Table P12-26. Determine a “best fit” bi nary interaction parameter that best matches the equation of state pressures to the experimental pressures. Plot those new predictions on the same curve. Comment on your results.
