5. In an experimental study of the absorption of ammonia by water in a wetted-wall column, the overall mass-transfer coefficient, KG was found to be 2.74109kgmol/m2sPa. At one point in the column, the gas phase contained 8mol% of ammonia and the liquid-phase concentration was 0.064 kgmol ammonia m3 of solution. The tower operated at 293K and 1.013105Pa. At that temperature. the Henry's law constant is 1.358103Pa(kg mol /m3). If 85% of the total resistance to mass transfer is encountered in the gas phase, determine the individual film mass-transfer coefficients, (10%) the interfacial compositions. (10%)
