Immiscible Liquids Phase Diagrams: Example Problems

Try to solve these problems before watching the solutions in the screencasts.

Example Problem 1

A gas mixture is 0.75% A and 25% B. 
As the pressure increases isothermally, component A condenses at 1.6 bar. 
At 2.4 bar, B starts to condense. 

 What are the saturation pressures of A and B?

Example Problem 2

6 mol A and 4 mol B are in equilibrium at 100°C and 2.0 atm.

A and B are completely immiscible in the liquid phase. 

Their vapor pressures at 100°C are:
