An air-SO2 gas mixture containing 3% SO2 by volume is contacted with water (B) containing 0.026% SO2 (A) by moles at 760 mmHg and 20C. Film mass transfer coefficients were calculated as kx =6.4*10-3 kmol/m2.s and ky =3.6*10-4 kmol/m2.s. The equilibrium data were obtained as follows.

Accordingly; a) Interface concentrations, (b) the total molar flow of SO2; c) Calculate the resistance in the gas phase to mass transfer.
