its a mass transfer question

The equilibrium solubility of Sozin water at 30C is given as: Pso2 (mm Hg) 0.6 1.7 4.7 8.1 11.8 19.7 36 52 79 g SO2 per 100 g H2O 0.02 0.05 0.1 0.15 0.2 0.3 0.5 0.7 1.0 At a point in an absorption column operating at a total pressure of 4.5 bar, the bulk concentrations in the gas and the liquid phases are x=0.0014 and y=0.02. The individual gas phase and liquid phase mass transfer coefficient are 80 and 15 kmol/(m2 h), respectively. Calculate: a. The interfacial concentrations at the particular location b. The overall mass transfer coefficients C. The rate of absorption d. The individual driving forces at the location in terms of mole fraction and concentrations e. The overall driving forces at the location in terms of mole fraction and concentrations f. What fraction of the total resistance is offered by the gas-film
