Estimate the enhancement of the mass transfer rate for SO2 absorption. For SO2, the pertinent reactions are SO₂(g)+H₂O H₂SO, H₂SO, 2 HSO, +H* HSO, SO₂+H* At neutral pH, H2SO3 rapidly dissociates, and the SO2 reaction with water becomes pseudo-first order, given as SO₂- products For SO₂, the rapid hydrolysis reaction dramatically enhances the rate of absorption. The first-order rate constant ki at 20°C is 3.4 x 106 s-1
