Kinetics of the formation of hydroxylamine disulfonate by reaction of nitrite with sulfites

The reaction between nitrite and bisulfite to form hydroxylamine disulfonate has been investigated and found to consist of three concurrent processes.TI1e reaction rate law can be expressed as•-• dt ~The values for the speci rate constants k 0 , k 1 , and k 11 (at 295 K and ~ = 5 3 -3 2 2 L20) are 8 x 10", 3,8 x 10 , and 9.6 x 10 liter /mole -sec, respectively.The of the rate constants k 1 and kii on temperature and ionic strength were investigated.A reaction mechanism has been proposed which is consistent with these results.The rate constants for the three rate determining steps in s mechanism have been calculated.
