Since NH3 gas does not dissolve at a boundary, it diffuses in N2, which does not spread. Total pressure is 1,013x105 Pa and temperature is 298 K. Partial pressure of NH3 at one point is 1,333x104 Pa and 20 mm further at another point 6,666x103 Pa. For the mixture at 1,013x105 Pa and 298 K, the spreadability is DAB = 2.30x10-5 m2/s. a) The flux of NH3 is kg.mol / s. Calculate in m2. b) Repeat (a), assuming that N2 is emitted. So both boundaries are it is permeable to gas and the flux is equimolar opposite propagation. In what state flux more is great?

Question
Since NH3 gas does not dissolve at a boundary, it diffuses in N2, which does not spread. Total pressure is 1,013x105 Pa and temperature is 298 K. Partial pressure of NH3 at one point is 1,333x104 Pa and 20 mm further at another point 6,666x103 Pa. For the mixture at 1,013x105 Pa and 298 K, the spreadability is DAB = 2.30x10-5 m2/s.
a) The flux of NH3 is kg.mol / s. Calculate in m2.
b) Repeat (a), assuming that N2 is emitted. So both boundaries are it is permeable to gas and the flux is equimolar opposite propagation. In what state flux more is great?
