The solute A is being absorbed from a gas mixture of A and B in a wetted-wall tower with the liquid flowing as a film downward along the wall. At a certain point in the tower, the bulk gas concentration yAG=0.25mol fraction and the bulk liquid concentration is xAL=0.05. The tower is operating at 298K and 1.013105Pa, and the equilibrium data are as follows: The solute A diffuses through stagnant B in the gas phase and then through a non-diffusing liquid. ky=1.465103kgmolA/sm2molfrac. kx=1.967103kgmolA/sm2molfrac. Calculate: a) Interface concentrations yAi and xAi and flux NA. b) Overall mass-transfer coefficients Ky and Ky and flux NA. c) Overall mass-transfer coefficient K and flux NA
