Solution: Calculate the entropy change for the vaporization of liquid methane and liquid hexane using the following data.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 ΔSvap for these liquids?

Problem

Calculate the entropy change for the vaporization of liquid methane and liquid hexane using the following data.

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 ΔSvap for these liquids?
