| Abstract: | The kinetic model for determining the non- isothesmal
mechanism of decomposition reaction of solid has been proposed.According to this, the reaction kinetics of the decomposition of calcium carbonate has been investigated. It has been shown that the decomposition of calcium carbonate in the conditon of different rate of heating-up is controlled by different reaction mechanism. Meanwhile, the active energy of the decompostion of condition carbonate is decreased with the increment in the rate of heating-up. |
