(a) Determine the specific enthalpy (kJ/mol) of n-hexane vapor at 200°C and 2.0 atm relative to n-hexane liquid at 20°C and 1.0 atm, assuming ideal gas behavior for the vapor. Show clearly the process path you construct for this calculation and give the enthalpy changes for each step. State where you used the ideal gas assumption

(b) What is the enthalpy of n-hexane liquid at 20°C and 1.0 atm relative to n-hexane vapor at 200°C and 2.0 atm? (This part should not take much time to complete.)

(c) Beginning with the value of ii calculated in part (a) and still assuming ideal gas behavior determine the specific internal energy of the vapor at 200°C and 2.0 atm. Once again, state where you used the ideal gas assumption.
