QJ$(40/100).$ 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 $y_{AG}=0\mathrm{.}30$mol fraction and the bulk liquid concentration is $x_{AL}=0\mathrm{.}10.$ The equilibrium

data of the process is given below. The solute $A$ is diffusing by equimolar counterdiffusion in tower.

The film mass$-$transfer coefficient for $A$ in the gas phase is predicted as; $k_y^{\text{'}}=5{10}^{-3}$kgmo$\frac{l}{s^2}{m}^2*mo{l}^{-}$

frac. for the liquid phase as $k_x^{\text{'}}=1{10}^{-3}$kgmo$\frac{l}{s^2}{m}^2.$ mol frac. Calculate

a$)$ The interface concentrations $y_{Ai}$ and $x_{Ai}$

b$)$ The molar flux $N_A$

c$)$ The overall mass transfer coefficient $K_y^{\text{'}}$ and $K_x^{\text{'}}$
