erface Problem $1$

The gas $A$ is being absorbed in a absorption tower. At a certain point in the tower the bulk gas concentration is $YA=0\mathrm{.}6$ mole fraction and $x=0\mathrm{.}08$ mole fraction. From the correlations for towers and for dilute solutions, the film mass transfer coefficient for gas A are $k^{\text{'}}x=1\mathrm{.}2mo\frac{l}{h}r.c{m}^2$ and $k^{\text{'}}y=1\mathrm{.}6mo\frac{l}{h}r.c{m}^2,$ and the overall mass transfer coefficient are $K_y^{\text{'}}=0\mathrm{.}35mo\frac{l}{h}r.c{m}^2$ and $K_x^{\text{'}}=1\mathrm{.}037mo\frac{l}{h}r.c{m}^2$

If the interface point $(x_{Ai},y_{Ai})=(0\mathrm{.}273,0\mathrm{.}52),$ calculate Resistance in gas film for equimolar case

a$)22\%\frac{1}{k^{\text{'}}y}$

b$)39\%$

c$)45\%$

d$)55\%$

Calculate the overall point $(x_A^{**},y_A^{**})$ from the following figure :

a$)(0\mathrm{.}3,0\mathrm{.}1)$

b$)(0\mathrm{.}3,0\mathrm{.}3)$

c$)(0\mathrm{.}1,0\mathrm{.}3)$

d$)(0\mathrm{.}1,0\mathrm{.}5)$
