These simulations lead you through the construction of pressure-composition and temperature-composition phase diagrams for immiscible liquids in a step-by-step procedure. Use these simulations to test your understanding. At the end of the quiz, you may view your grade by pressing “Show Score” or restart the simulation with randomized parameters by pressing “Restart Problem”. The “Submit for Grade” and “Give Feedback” buttons are no longer supported. Instead, email LearnChemE@gmail.com to provide feedback.
