Table B.2 of Appendix B provides parameters for an equation that gives P sat as a function of T for a number of pure compounds. For one of them, determine the heat of vaporization at its normal boiling point by application of Eq. (4.1), the Clapcyron equation. Evaluate dP sat/dT from the given vapor-pressure equation, and use generalized correlations from Chap. 3 to estimate ( V. Compare the computed value with the value of (Hn listed in Table B.2. Normal boiling points arc listed in the bat column of Table B 2.
