Using a Cubic EOS to Determine Vapor-Liquid Equilibrium: Interactive Simulation
This simulation will run on your browser. Try to predict the behavior when a parameter changes before using a slider to change that parameter. A screencast below explains how to use this simulation.
Peng-Robinson EOS for Mixtures
Try to answer these questions before determining the answer with the simulation. We suggest that you write down the reasons for your answers.
- For a liquid mixture of n-butane and n-octane, as the mole fraction of n-butane increases at constant temperature, how does the bubble pressure change?
- For a liquid mixture of n-butane and n-octane, as the temperature increases, does the pressure for vapor-liquid equilibrium increase or decrease?
