Chlorine water for pulp bleaching is being prepared by absorption of chlorinein water in a packed tower operating at 20 °C and atmospheric pressure. Atone point in the tower the chlorine partial pressure is 0.5 atm and theconcentration in the liquid is 1 kg m-3. The molecular weight of chlorine is 71and it may be assumed that the density of the liquid is the same as that of thewater (1000 kg m-3). Data on the solubility of chlorine in water expressed inmole fractions are presented in Table Q3 belowIf 85% of the resistance to mass transfer lies in the liquid phase,calculate the interfacial compositionsY=3.1X
