this is a mass transfere question

Q1. Ammonia (A) diffuses through a stagnant layer of air (B), 1cm thick, at 2) latm total pressure. The partial pressures of NH4 on the two sides of the air layer are PN=0.9 atm and PAO=0.1 atp respectively; DAB=0.214cm2/s. Air is non-diffusing. Take R=82.1cm3stm/K, mole). Calculate: (a) The molar flux of NH3. (b) The velocities of the individual components with respect to a stationary observer. (c) The molar and the mass average velocities of the components. Q2. A continuous fractionating column is to be designed to separate 2.5kg/s of a
