1) Calculate the entropy change for the vaporization of liquid methane and liquid hexane using the following data
Methane CH4 -- Boiling point= 112K Delta H(vap) = 8.20kJ/mol
Hexane C6H14 -- Boiling point= 342 Delta H(vap) =28.9 kJ/mol
2) compare the molar volume of gaseous methane at 112 K with that of gaseous hexane at 342 K. How do the difference in molar volume affect the values of delta S(vap) for these liquids?
