Abstract
Study of the kinetics of sulfur dioxide oxidation by iron(III) (the systems FeCl/sub 3/-HClO/sub 4/-H/sub 2/O,FeCl/sub 3/-HClO/sub 4/-Kl-H/sub 2/O, and FeCl/sub 3/-HClO/sub 4/-LiCl-H/sub 2/O) showed that the introduction of iodide and chloride ions raises the activity of the system. The proposed mechanism of oxidation postulates the formation of the thionate radical (HSO/sub 3/). The reaction order was determined to be 1 with respect to the oxidizing and reducing agents and iodide ions, and 0.5 with respect to chloride ions. The calculated activation energies were determine to be 68.9 kJ/mole (H/sub 2/O), 44.0 kJ/mole (with chloride ions), and 37.5 kJ/mole (with iodide ions).
