Abstract: A new method for determination of reaction order n by DTG curve is presented in this paper. The reliability of the method is illustrated by the investigation of the decomposition process of CaC_2O_4·H_2O. The result shows that the peak area of DTG Curve corresponds to the change of sample weight. The reaction order n may be determined by the following equation: 1-x_m=1/e (n=1); 1-x_m=n~(1/(1-n)) (n≠1)Where x_m represents the fraction reacted at maximum rate of the reaction, x_m can be calculated by the ratio of sample changed at the top of DTG peak ...
