Predict the Txy behavior for a mixture of n-hexane (1) + p-xylene (2) at 101.33 kPa using the Peng Robinson equation of state. Compare the predictions to the experimental data, as given in Table P12-20. Is the Peng-Robinson equation of state a reasonable model for this system at this state? Please explain.
