Chapter 1
The point of this problem is just for you to practice evaluating and plotting a simple function.
You will do a number of problems over the course of the semester (and many more over the
course of your career) in which the results are best presented in graphical form. The only thing to
be careful of in plotting the Antoine equation is to pay attention to the units of T and Psat and to
whether the constants are given for use with the base 10 logarithm or the natural logarithm. The
parameters in Table B.2 are for use with T in °C, P in kPa, and the natural logarithm.
I used MS Excel to prepare the plots for diethyl ether. A portion of the spreadsheet (containing
the plots) is shown below:
