The vapor pressures of the components, A and B, in a binary solution have been modeled and found to obey PA = XAPA* exp(XB²) PB = XBPB* exp (X₁²) where XA and XB are the mole fractions, and PA* and PB* are the vapor pressures of each pure substance. (a) If PA* = 0.175 bar and PB* = 0.126 bar, compute the total vapor pressure (in bars) of the mixture when XB = 0.68. (b) Assuming that the vapor is an ideal gas, what are the mole fractions of each component in the vapor phase?

The binary water-phenol diagram is given below, in molar fraction, under the total pressure Pt = 1 atm. 1) How many phases are there in the domain marked "I"? 2) From which temperature the mixture become miscible in all proportions? How do you call that temperature? 3) At a temperature T = 50 °C, in a controlled temperature container containing water. Phenol is then poured at the same temperature until the molar fraction of phenol in the mixture XC2H50H is equal to 0.05. Then, we continue to add the phenol gradually, at a constant temperature, to XC2H5OH of phenol in the mixture is XC2H5OH = 0.8. = 0.4. Then finally we stop adding phenol when the molar fraction a.
