Use the Try and Pay diaguas in your textbook.
a) What is the compoution(mole fractions) of the vapor? (5 pts)
b) what is the dew point of a 60 mole% benzene and 40 mole% toluene vapor at 1 atm?
c) what is the condensate composition (mole fractions)?

Explanation / Answer

To calculate the boiling point of a 30 mol% benzene and 70 mol% toluene, we need the phase diagram of benzene-toluene mixture.

From the diagram, (refer the link)

Boiling point is 103C

a) Vapor composition at 103C is 50mol% each

b) dew point of 60 mol% benzene and 40mol% toluene is 96C

c) liquid composition would be 39mol % benzene and 61 mol% toluene
