A wastewater stream is introduced to the top of a mass$-$transfer tower where it flows countercurrently to an air stream. At one point in the tower, the wastewater stream contains $1x{10}^{-3}$mol of $\frac{A}{m^3}$ and the air is essentially free of any A$.$ At the operating conditions within the tower, the film mass transfer coefficients are $k_x=5{10}^{-4}$kmo$\frac{l}{m^2}s(kmo\frac{l}{m^3})$ and $k_y=0\mathrm{.}01$ kmo$\frac{l}{m^2}$satm. The concentrations of A are in the Henry's law region where $p_A=HC{C}_A$ with $H=10at\frac{m}{\text{k}\text{m}\text{o}\frac{l}{m^3}}.$

Determine:

$($i$)$ the overall molar flux of $A$

$($ii$)$ the overall mass transfer coefficients, $K_x$ and $K_y$

$($iii$)$ the percentage of mass transfer resistance that lies in the gas phase
