In addition, it is also clear from Table 2 that kinetic parameters obtained from a single experimental curve are strongly dependent on the n coefficient previously assumed. Fig. 1 confirms the above conclusion; thus, this figure includes three DSC (or DTA) traces computed for linear heating rate conditions, n ? 2, 2.5 and 3, and the kinetic parameters obtained from Table 2. It is clear from this figure (Fig. 1) that the three curves simulated assuming different kinetic parameters overlap completely,and it is not possible to differentiate among them from a single DSC (or DTA) trace.
