The molar enthalpy of vaporization of benzene at its normal boiling point (80.09° C) is 30.72 kJ mol. Assuming that Avap Hm and AvapSm stay constant at their values as 80.09•C, calculate the value of AvapGm at 75.0°C, 80.09•C, and 85.0°C. What do the values of vap Avap vapGm tell you about the spontaneity of the vaporization at these three temperatures?

Question
The molar enthalpy of vaporization of benzene at its normal boiling point (80.09° C) is 30.72 kJ
mol. Assuming that Avap Hm and ApapSm stay constant at their values as 80.09•C,
calculate the value of AvapGm at 75.0°C, 80.09°C, and 85.0°C. What do the values of
-1
Avap Gm tell you about the spontaneity of the vaporization at these three temperatures?
