A vapor mixture contains benzene (C6H6) and 10.0 mole% toluene (C7H8) at 110°C and 1.00 atm. A continuous stream of this vapor mixture enters a separator at 15.0 mol/hr. The streams exiting the separator are at a dew point (90°C and 1.25 atm). The liquid and vapor leaving the separator can be considered in equilibrium. The vapor leaving the separator is then heated isobarically to 130°C.(a) Draw a process flow diagram, number the streams, and label the phase of each stream (solid, liquid, gas).(b) Calculate the flow rate (mol/hr) and mole fractions of the liquid that exits the separator.(c) Calculate the volumetric flow rate (m3/hr) at standard temperature and pressure (STP) conditions of the vapor stream that exits the heater.(d) An alternative solution could use the dew point pressure form of Raoult's law. Derive the expression for the vapor mole fraction of exiting benzene, and check the answer with the previous solution.(e) The separator breaks down making the process isobaric. Will the benzene composition of the liquid leaving the separtor increase, decrease, or stay the same?
