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 D_AB = 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?
