A vapor mixture containing 30 mole% benzene and 70% toluene at 1 atm is cooled isobarically j, a closed container from an initial temperature of 115°C. Use the Txy diagram of Figure 6.4-1 to answer the following questions.

(a) At what temperature does the first drop of condensate form? What is its composition?

(b) At one point during the process the system temperature is 100°C. 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.
