Transcribed Image Text: Estimating Temperature (or Vapor Pressure) For benzene (C6H6), the normal boiling point is 80.1 °C and the enthalpy of vaporization is 30.8 kJ/mol. What is the boiling point of benzene in Denver, where atmospheric pressure = 83.4 kPa? 101.325 kPa In P₁ P2 AHvap 1 R T₂ T₁ P₁ = 1.00 atm x 101.325 kPa/atm T₁ = 80.1 °C + 273.15 = 353.25 K 1 In 101.325 83.4 P₂ ...
Four hundred and fifty lbmol/h (204 kmol/h) of a mixture of 60 mol% benzene (LK) and 40 mol% toluene (HK) is to be separated into a liquid distillate and a liquid bottoms product of 95 mol% and 5 mol % benzene, respectively. The feed enters the column with a molar per- vaporization equal to the distillate-to-feed ratio. Use the McCabe-Thiele method to compute, at 1 atm (101.3 kPa): (a) Nmin ...
A beaker filled with an equimolar liquid mixture of ethyl alcohol and ethyl acetate evaporates at 0°C into still air at 101 kPa (1 atm). Assuming Raoult's law, what is the liquid composition when half the ethyl alcohol has evaporated, assuming each component evapo- rates independently? Also assume that the liquid is always well mixed.

During a trip to the beach (Patm = 1 atm = 101.325 kPa), a car runs out of gasoline, and it becomes necessary to siphon gas out of the car of a Good Samaritan. The siphon is a small-diameter hose, and to start the siphon it is necessary to insert one siphon end in the full gas tank, fill the hose with gasoline via suction, and then place the other end in a gas can below the level of the gas ...
