CHE425: Problem set #31) 1A mixture of 100 mol containing 60 mol % n-pentane and 40 mol % n-heptane isvaporized at 101.32 kpa abs until 40 mol of vapor and 60 mol of liquid in equilibrium witheach other are produced. This occurs in a single-stage system and the vapor and liquid arekept in contact with each other until the vaporization is complete. Calculate the compositionof the vapor and liquid. The equilibrium data are follows, where x and y are mole fraction ofn-pentane.x 0 0.059 0.145 0.254 0.398 0.594 0.876 1.000y 0 0.271 0.521 0.701 0.836 0.925 0.984 1.0002) We have 0.01 moles (N1) of drug dissolved in 100 moles of water (N3). We then add to thisphase 50 moles (N2) of octanol. The octanol-water partition coefficient for the drug is 89. Ki = IiIIixx = 89For this system, octanol (phase I) and water (phase II) are immiscible. Estimate the molefractions of the drug in the two phases once equilibrium has been attained and the %extraction of the drug from the aqueous phase.23 3) Benzylpenicillin is an older antibiotic effective against pneumococcal and meningoccalinfections, anthrax, and Lyme disease. As part of a purification process, 100 mg ofbenzylpenicilin is mixed with 25 ml of n-octanol and 25 mL of water. After equilibrium isestablished, there is a water-rich phase that contains essentially no n-octanol and an octanol-rich phase that contains 74 mol % n-octanol and 26 mol % water. Determine theconcentrations of benzylpenicillin in each of these phases24 Data: The molecular weight of benzylpenicillin is 334.5, that of n-octanol is 130.23, theliquid density of n-octanol is 0.826 g/cm3, and KOW,B = OBWBCC = mg B/(ml n-octanol)mg B/(ml water)= 65.54) A drug is in an aqueous (phase II) stream flowing at 100 moles/min at a drug mole fractionof 0.01. The aqueous stream is then contacted with an extractor with a pure solvent (phase I)flowing at 120 moles/min. The distribution coefficient for this particular drug is given byKi = IiIIixx = 611 Geankoplis, C.J., Transport Processes and Separation Process Principles, 4th edition, Prentice Hall, 2003, p. 7052323 Fournier, R.

A very slight amount of nonvolatile impurity is dissolved in theorganic. To purify the ethylaniline, it is steam-distilled by bubbling saturated steam into themixture at a total pressure of 101.32 kPa. Determine the boiling point of the mixture and thecomposition of the vapor. The vapor pressure of each of the pure compound is as follows:Temperature(oC) PA(water, kPa) PB(ethylaniline, kPa)80.6 48.5 1.3396.0 87.7 2.6799.15 98.3 3.04113.2 163.3 5.336) Vapor-liquid equilibrium for the system A-B at a constant temperature of 80oC shows thatcomponent B obeys Henry’s law in the range 0 < xB  0.020.
