We introduce the Clausius - Clapeyron equation and show how it accounts for the vapor pressure of a liquid as a function of temperature. (Oxtoby Figure 5-15). Once we have this diagram we can use it to understand both simple and fractional distillation.
We next use the spreadsheet to prepare phase diagrams such as those in figures 5-19 and 5-21. We use the Clausius-Clapeyron equation developed above.
(3) To prepare for this lab you should read Oxtoby, Chapter 5, paying special attention to the figures cited above.
