Abstract: We review and discuss kinetic studies of the disproportionation reaction of iodous acid (HIO2) in the presence of excess of Hg 2+-ions. The reactions are followed at different temperatures in water solution with strongly defined acidity. The rate constants of disproportionation are determined between 285 and 303 K based on kinetic data obtained under steady-state conditions. The calculated rate constants increase with increasing temperature and acid concentration. The corresponding values of activation energy as well as enthalpy and entropy of activation for this reaction have been calculated. The enthalpy of activation as well as entropy is higher at higher sulfuric acid concentration. Also, it was considered that the values of Gibbs energy of formation of HgI+ are generated during the process. © 2010 Wiley Periodicals, Inc.
