An absorption tower, operating at $20C$ and $1$atm pressure, was used to absorb $S{O}_2$ from an air mixture into water. At one point in the equipment the partial pressure of the $S{O}_2$ in the gas stream was $30mmHg,$ and the concentration of the contacting liquid stream was $0\mathrm{.}0344$ IbmolS$\frac{O_2}{f}{t}^3$ of solution. The individual film mass$-$transfer coefficients at $20C$ and $1$atm, were of solution $)$ and $k_G=0\mathrm{.}065$lbmo$\frac{l}{h}r.f{t}^2.mmHg.$ Equilibrium data at $20C$ are as below:
