The Antoine equations for benzene and toluene are given as follows: Ln(P)=AT+CB, where P is in mmHg and T is in Kelvin. For benzene: A=11.513,B=723.983,C=204.958 For toluene: A=14.130,B=2068.798,C=107.940 Construct a P-x-y diagram at 100C, calculate the dew point pressure of a 4060mol% benzene- toluene vapor at 100C, and determine the mole fraction of the first condensate obtained from that vapor.
