In an experimental study of absorption of ammonia by water in a wetted wall column. The overall gas phase mass transfer coefficient KG was estimated as 2.72 x 104 kmoles/m² atm. At one point in the column the gas contained 10 mole % ammonia and the liquid phase concentration was 6.42 x 10-² kmoles NH3 /m³ of solution. Temperature is 293 K and the total pressure is 1 atm. 85% of the resistance to mass transfer lies in gas phase. If Henry's law constant is 9.35 x 10-³ atm. m³/kmole, calculate the individual film coefficient and the interphase composition. Also estimate the molar flux.
