Q.2. (a) Determine the specific enthalpy (kJ/mol) of n-hexane vapor at 200C and 2.0atm relative te n-hexane liquid at 20C and 1.0atm, 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 20C and 1.0 atm relative to n-hexane vapor at 200C and 2.0atm ? (This part should not take much time to complete.) (c) Beginning with the value of H^ calculated in part (a) and still assuming ideal gas behavior, determine the specific internal energy of the vapor at 200C and 2.0atm. Once again, state where you used the ideal gas assumption
