Answer the following questions. a. A substance is found to have S0 vap =110Jmol1K1. Using Trouton's rule as a framework, describe the key chemical characteristics of this substance that contribute to it having this value for S vap. b. A substance is found to have S vap =60Jmol1K1. Using Trouton's rule as a framework, describe the key chemical characteristics of this substance that contribute to it having this value for S vap. c. An unidentified compound has Hvap=55.0kJ/mol and a boiling point of 185 C. Based on this information, comment on the relative strength of intermolecular interactions and extent of ordered structure in the liquid phase. (A calculation may be helpful to justify your answer.) d. Which one of the linear-shaped molecules below forms a crystal structure that is more likely to have S=0J/K at 0K,FCN or NNO ? Why? e. Which would you expect to have a higher molar entropy at T=0K, single crystals of CBr4 or of CBr3F ? Why
