Q) A drum that has been used to collect hazardous waste contains an organic phase in which the mole fractions of benzene, toluene, and o-xylene are 0.32, 0.27, and 0.21, respectively. At the ambient temperature of 25°C, the vapor pressures of these three chemicals are 0.126, 0.038, and 0.012 atm.
(a) If the organic phase behaves ideally with respect to Raoult's law, estimate the partial pressures of the three major constituents in the head space in the drum.
(b) Some rain water that has leaked into the drum and is present as a separate phase. If Henry's law applies to this phase, what are the mole fractions of the three constituents in the aqueous solution
