Lever Rule: Interactive Simulations
These simulations will run on your browser. Try to predict the behavior when a parameter changes before using a slider to change that parameter. Screencasts below explain how to use these simulations. Â
Lever Rule for a Binary Mixture on P-x-y Diagram
Try to answer these questions before determining the answer with the simulation. We suggest that you write down the reasons for your answers.
- Suppose liquid and vapor are in equilibrium for a binary mixture whose liquid is an ideal solution. When the overall mole fraction of the more volatile component increases at constant temperature and pressure, does the amount of vapor increase or decrease?
- Suppose liquid and vapor are in equilibrium. When the pressure increases at constant temperature, does the amount of vapor increase or decrease?
Try to answer these questions before determining the answer with the simulation. We suggest that you write down the reasons for your answers.
- Pure Ti(s) is in equilibrium with a Ti-U liquid mixture. How do the amounts of each phase change when the temperature increases (the overall composition does not change)?
- Are there places on the diagram where the lever rule does not apply?
