Sulfur dioxide (A) is being absorbed into water in a packed column, where bulk conditions
are 50°C, 2 atm, yAb= 0.08, and x4b = 0.001, whereas the liquid concentration is estimated
to be 55 kmol/m³. Experimental values of the mass transfer coefficients are: k.=0.18 m/hr,
kg = 0.04 kmol/ (hr-m²-kPa). The equilibrium data for the system is plotted as in Fig.-Q1:
