Description	The decomposition rate of sodium hydrogen carbonate (NaHCO3) into carbonate (Na2CO3) was determined as weight loss at ambient pressure and elevated temperatures up to 230 °C. A particularly slow increasing-temperature procedure and small samples of fine powders were employed to minimize heat and mass transfer intrusions. Efficient removal of the gaseous products eliminated possible equilibrium constraints. A near-first-order reaction rate equation has been presented for the decomposition reaction and also verified by the data collected by experiment in a constant-temperature mode. This correlation makes it possible to predict the reaction rate as a function of temperature and the extent of decomposition. In combination with its integrated form, it can readily be used, for example, in modeling or design of the decomposition proces.
