I do notice that there's no hydrogen involved in the equation, but maybe the reaction occurs in an acidic medium? What are the oxidation states of sulfur in the tetrathionate ion? The iodine produced in this reaction (R1) is, as it is formed, reduced back to iodide by the thiosulfate: 2S 2O 3 2-+ I 2 → 2I-+ S 4O 6 2-(R2) ... solution and exp-E/RT as the Boltzmann factor which gives the fraction of the molecules with sufficient energy, E, to react.
