Adding a Second Component to a Single-Component Vapor-Liquid Equilibrium (VLE) Mixture
Initially, 20 mol of liquid and 0.1 mol of vapor are in equilibrium in a cylinder with a movable piston. The system initially contains only n-hexane and n-octane is injected when the “inject isothermally” play button is pressed, or it starts with n-octane and n-hexane is injected. Change the number of moles injected at constant temperature and pressure with a slider. The system is modeled by Raoult’s law. The P-x-y diagram explains why the final state is all liquid or vapor. Use the “reset” button to start the process again.
