P7.29 Styrene is the building block for polystyrene, a polymer that enjoys

ubiquitous use in products such as coffee cups and packaging "peanuts."

Styrene is made by dehydrogenation of ethylbenzene. Since reactor

conversion is much less than 100%, a separation between styrene and

ethylbenzene is needed. Using Antoine equations to calculate saturation

pressures along with Raoult's law, calculate

(a) the boiling point temperature of pure styrene at 2 bar,

(b) the boiling point temperature for pure ethylbenzene at 2 bar, and

(c) the dew point and bubble point temperatures for a 50:50 (mol:mol)

mix of styrene-ethylbenzene system at 2 bar.
