Question:
In the absorption of component A (molecular weight $=60$ ) from an airstream into an aqueous solution, the bulk compositions of the two adjacent streams at a point in the apparatus were analyzed to be $p_{A, G}=0.1 \mathrm{~atm}$ and $c_{A, L}=1.0 \mathrm{kmol}$ of $\mathrm{A} / \mathrm{m}^{3}$ of solution. The total pressure was $2.0 \mathrm{~atm}$; the density of the solution was $1100 \mathrm{~kg} / \mathrm{m}^{3}$. The Henry's law constant was $0.85 \mathrm{~atm} / \mathrm{mol}$ fraction. The overall gas coefficient was $K_{G}=0.27 \mathrm{kmol} / \mathrm{m}^{2} \cdot \mathrm{h} \cdot \mathrm{atm}$. If $60 \%$ of the total resistance to mass transfer resides in the gas film, determine
(a) The gas-film coefficient, $k_{G}$
(b) The liquid-film coefficient, $k_{L}$
(c) The concentration on the liquid side of the interface, $x_{A, i}$
(d) The mass flux of A
