In an apparatus for the absorption of $S{O}_2$ in water at one point in the column the concentration of $S{O}_2$ in gas phase was $)=(0\mathrm{.}11$ in contact with a liquid with $x_N.=0\mathrm{.}001$ as shown in the following graph. Pressure and temperature are $1$ atm $(1\mathrm{.}013{10}^5\frac{N}{m^2})$ and $298K,$ respectively. The overall gas phase mass transfer coefficient $(K_0)$ is $6\mathrm{.}25{10}^{-10}mo\frac{l}{m^2}s.($N$/$m $(\frac{\text{:}}{m^2}\}.$ Of the total resistance $40\%$ lies in gas phase and $60\%$ in the liquid phase. Answer questions $8-13.$
