5. The gas "A" is absorbed into a completely stationary liquid phase where the reaction A → B occurs, characterized by the first order rate constant, k1. Let the gas-liquid interface correspond to z = 0, where the solubility of A is known. The liquid extends in the positive z-direction. The rate of reaction is much greater than the rate of diffusion, thus it can be assumed that CA O as z becomes large. Assume one dimensional diffusion. AB a....

One means of producing liquid oxygen from atmospheric air is to
take advantage of the phase equilibrium properties of
oxygen-nitrogen mixtures. This system is illustrated in Fig.
P16–121. In this cascaded-reactors system, dry atmospheric air is
cooled in the first reactor until liquid is formed. According to
the phase-equilibrium properties, this liquid will be richer in
oxygen than in the vapor phase. The vapor in the first reactor is
discarded while the oxygen enriched liquid leaves the first reactor
and...
