Use the diagrams below to help us understand the systems.

Must show work on the diagram for full credit.

1. If a 30% ethanol liquid solution in water was mixed and heated at what temperature would the bubble point occur? What is the composition of ethanol for the vapor that would be in equilibrium with this liquid?


2. What is the dew point of a vapor that is 20% ethanol? What is the composition of the water in the liquid that is in equilibrium with this vapor?
