Question:

Estimate the heat of vaporization (kJ/mol) of benzene at 25°C, using each of the following correlations and data:

(a) The heat of vaporization at the normal boiling point and Watson’s correlation.

(b) The Clausius–Clapeyron equation and boiling points at 50 mm Hg and 150 mm Hg.

(d) Find a tabulated value of the heat of vaporization of benzene at 25°C. (Suggestion: Do the same thing you do when you want to find almost any item of information.) Then calculate the percentage errors that result from the estimations of Parts (a), (b), and (c).
