ChE131/141L Fitting a Straight Line to Data Fall 2006 C.L. Caenepeel This data may be curve fit with either of the following two models: Clausius Clapeyron Equation Antoine Equation Assume that you are given vapor pressure as a function of temperature data. Explain how you would use this data to find the two constants (k &A ) in the Clausius Clapeyr Explain how you would use this data to find the three constans (A,B & C) in the Antoine equa 2. Apply your above methods to the following data for 1-chlorotetradecane at several temperatures. Solve this problem with Excel & MATLAB T(oC)

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
