Calculate Temperature Of Condensation Of Benzene And Toluene Vapors
Question
A vapor mixture containing 30 mol% benzene and 70 mol% toluene at 1 atm is cooled isobarically in a closed container from an initial temperature of 115°C.
(a) At what temperature does the first drop of condensate form and what is its composition?
(b) At one point during the process the system temperature is 100ºC. Determine the mole fractions of benzene in the vapor and liquid phases and the ratio (total moles in vapor/total moles in liquid) at this point.
(c) At what temperature does the last bubble of the vapor condense? What is its composition?
Summary
The question belongs to Chemical Engineering and it discusses about calculation of temperature at condensation of benzene and toluene forms and the mole fractions of benzene in the vapor.
