Estimate the critical constants (T c , P c ), accentric factor ( ω ) and vapor pressure of pure caffeine as described in Problem 13.4 of the text. To solve this problem you will have to review the methods presented in Chapter 13 for predicting physical properties using molecular group contributions. (Note: Since the >N– (ring) group is not listed, use the >N– (non-ring) group in its place). 4. Problem 15.38 in the textbook. 5. Problem 15.29 in the textbook. Be sure to state and justify all assumptions made. Modified: 11/17/03...
