Question
Toluene vapors at 1.013 bar, 150°C, are cooled under constant pressure
to a final temperature of 22°C.
(a) Determine the amount of heat that must be removed
(b) How much heat must be removed if the final state is a vapor-liquid mixture that contains
60% vapor by mass.
Assume that Cp for vapor phase is a function of temperature, and for liquid toluene Cp is constant (= 155.96 J/(mol K)). The boiling temperature of toluene at 1.013 bar is 110.6°C, and standard heat of vaporization for toluene 38060 J/mol.
