Question 5. Carbon dioxide (CO2) gas is absorbed into water in a packed tower. The CO2 mass transfer coefficient on the gas side, given in terms of pressure, is 9.3 x 10-6 mol/(mas Pa) The CO2 mass transfer coefficient on the liquid side, given in terms of mole fraction, is 1.2 mol/(ms). The Henry's law constant is 7.6 x 106 Pa for CO2. (a) Write down expressions describing the flux of CO2 to the gas/liquid interface from (i) the gas...

In an experimental study of the absorption of NH3 by water in a wetted-wall column, the value of KG was found to be 0.205 lbmole NH3/hr.ft2.atm. At one point in the column, the gas contained 8 mole percent NH3 and the liquid phase concentration was 0.004 lbmole of NH3 per ft3 of solution. The temperature was 68 oF, and the total pressure was two atmospheres. Eighty-five percent of the total resistance to the mass transfer was found to be in...

Please be clear and readable thank you
Pr. 2 (20 pts) SO2 is absorbed from air to water at 20°C and 1 atm in a wetted wall column with 40 mm ID and 1 m length. A gas stream containing 3 vol- % SO2 and 97 vol- % air is fed to the column at the bottom with a mass velocity of 0.05 m®/min and flows upward. Exit gas stream contains 1 vol-% SO2. Pure water is fed to the...

Q2) In a collision of sufficient force, automobile air bags
respond by electrically triggering the explosive decomposition of
sodium azide (NaN3) to its elements. A 43.398 g sample
of sodium azide was decomposed, and the nitrogen gas generated was
collected over water at 22°C. The total pressure was 798.8 mmHg.
