Graphical estimation of reaction order

If two thermograms at different heating rates are obtained for the same material, the results can be treated according to the following procedure. From eqn. (72) one can readily derive 

The temperature limits Tx and T2 are identical for both thermograms, and x is an arbitrary constant. If x is taken as zero, 

Various other methods have been described and discussed by Reich and Levi [26], and a comparative study of some methods has been published by MacCallum and Tanner [35].
