The solute A through the gas mixture A and B is adsorbed by the liquid flowing down the wall like a film in a wet-walled column. At a given point inside the tower, the bulk gas concentration is yAG = 0.38 and the bulk liquid concentration is a fraction xAL = 0.16 moles. The tower operates at 298 K and 1.013x105 Pa, and the balance data is as follows.

xA	yA		xA	yA
0,000	0,000		0,250	0,170
0,050	0,025		0,300	0,220
0,100	0,050		0,350	0,280
0,150	0,085		0,375	0,335
0,200	0,125

The solute A diffuses through stagnant B in the gas phase and then through a liquid that does not diffuse. The film mass coefficient for A in the gas phase was calculated as ky' = 1.436x10-3 kgmol A/ s.m2.mol fraction and for the liquid phase kx' = 1.842x10-3 kgmol A/s.m2.mol fraction. Calculate the interface concentrations yAi and xAi, as well as the NA flux. (It will be solved by trial and error.)
