Abstract
Isothermal decomposition of KBrO3 has been studied as a function of concent ration of the dopants, SO42- and Ba2+ by isothermal thermogravimetry in the temperature range 668 - 683 K. The rate law and the activation energies re mained unaltered by doping. The results suggest a diffusion-controlled mech anism, the diffusing species being both K+ and BrO3-.
