In a wetted-wall column, the absorption of ammonia by water is taking place. The overall mass transfer coefficient, Ky was found to be 2.75106kmol/m2sy. At one point in the column, the composition of the gas and liquid phases were 11.0 and 0.105 mole\% NH3, respectively. Seventy five % of the total resistance to mass transfer was found to be in the gas phase. At 300K, Ammonia -water solutions follow's Henry's law upto 5 mole\% ammonia in the liquid, with m=1.64 when the total pressure is 1 atm. Calculate (a) the local liquid and gas phase mass transfer coefficients (b) the interfacial concentrations (c) The flux based on interfacial concentration (d) overall liquid phase mass transfer coefficient [2.5+2.5+2.5+2.5=10]
