Chapter 17, Problem 84AE
Calculate the entropy change for the vaporization of liquid methane and liquid hexane using the following data.
| Boilling point (1atm) | ∆Hvap | |
| Methane | 112K | 8.20 KJ/mol |
| Hexane | 342K | 28.9 KJ/mol |
Compare the molar volume of gaseous methane at 112 K with that of gaseous hexane at 342 K. How do the differences in molar volume affect the values of ∆Svap for these liquids?
