please answer clearly
1 (Lecture LOI) 50 m3 of a 35-C gas mixture with composition 98 miole percent air(3), 2 mole percent toluene(1) is contacted with 400 kg of 35°C pure n-decane(2). The vapor-liquid system is allowed to come to equilibrium isothermally at 35 oC at a constant pressure of 1.0 atm. What are the final compositions of the liquid and vapor phases? You should neglect dissolution of air in the liquid, but you must account for evaporation of n-decane....
The measurement of the compositions of the liquid and vapor phases
The measurement of the compositions of the liquid and vapor phases, in equilibrium, of acetone (A) and methanol (M) solutions showedthat, at 57.2 ºC, under a pressure of 1.00 atm, we have xA = 0.430 when yA = 0.536. Calculate the activities and coefficients ofactivity of the two components of this solution based on Raoult's law. Vapor pressures of pure components,at the temperature mentioned, they are: pA∗= 105 kPa and pM∗= 73.5 kPa. (xA is the molar fraction in the...

Hand Calculations (40 %)-(must not exceed 2 pages) The process involves the separation of a binary mixture containing heptane and ethylbenzene using a countercurrently operated continuous fractionation unit. A feed at a flowrate of 252 mol/h containing 43 wt% heptane and 57 wt% ethyl benzene is to be fractionated at 1 bar to give a distillate with 95 mol% heptane and a bottom product with 95 m0196 ethyl benzene. The reflux ratio will be 70% more than the minimum. The...

A mixture of 100 mol containing 60 mol% n-pentane and 40 mol% n-heptane is vaporized at 101.325 kPa abs pressure until 40 mol of vapor and 60 mol of liquid in equilibrium with each other are produced. This occurs in a single-stage system and the vapor and liquid are kept in contact with each other until the vaporization is complete. Calculate the composition of the vapor and liquid. The equilibrium data are as follows, where x and y aremole fractions...
