SO₂ is absorbed from air into water in a packed absorption tower, at room temperature. At a location in the tower, SO₂ is absorbed at the rate of 0.02 mol/m²h, with its liquid-phase mole fraction of 0.0025 at the gas-liquid interface, and 0.0003 in the bulk liquid. The diffusivity of SO₂ in water is 1.5 x10-6 cm²/s. a) If film theory is applicable, calculate the mass transfer coefficient and the film thickness. b) If penetration theory is applicable, calculate the contact time. c) If surface renewal theory is applicable, calculate the fractional surface renewal rate.
