Textbook Question
Chapter 19, Problem 107IE
Most liquids follow Trouton’s rule (see Exercise 19.95), which states that the molar entropy of vaporization is approximately 88 ± 5 J/mol-K. The normal boiling points and enthalpies of vaporization of several organic liquids are as follows:
| Substance | Normal Boiling Point (°C) | ΔHrap (kj/mol) |
| Acetone, (CH3)2CO | 56.1 | 29.1 |
| Dimethyl ether, (CH3)2O | -24.8 | 21.5 |
| Ethanol, C2H5OH | 78.4 | 38.6 |
| Octane, CSH|S | 125.6 | 34.4 |
| Pyridine, QHSN | 115.3 | 35.1 |
(a) Calculate ΔSo for each of the liquids. Do all the liquids obey Trouton’s rule? (b) With reference to intermolecular forces (Section 11,2), can you explain any exceptions to the rule? (c) Would you expect water to obey Trouton’s rule? By using data in Appendix B, check the accuracy of your conclusion, (d) Chlorobenzene (C46H5Cl) boils at 131.8 °C. Use Trouton’s rule to estimate ΔHvap for this substance.

At 0oC and 1 atm, the viscosity of hydrogen (gas) is 8.55x10-5 P. Calculate the viscosity of a gas, if possible, consisting of deuterium. Assume that the molecular sizes are equal.
Indicate the correct option for the velocity distribution function of gas molecules:a) its velocity cannot be measured in any other way due to the small size of the gas moleculesb) it is only used to describe the velocity of particles if their density is very high.c) it describes the probability that a gas particle has a velocity in a given interval of velocitiesd) it describes other magnitudes, such as pressure, energy, etc., but not the velocity of the molecules
