3.1.1. Kissinger Method

For a predetermined reaction order, the rate of decomposition can be plotted at the same conversion for different heating rates. Also the decomposition rate is maximum at peak temperatures (*Tp*).

$$\frac{d}{dt}\frac{d\alpha}{dt} = \frac{d}{dt}\left((1-\alpha)^n A e^{\frac{F}{RT}}\right) = 0\tag{4}$$

$$\ln \frac{b}{T\_p^2} = -\frac{E}{RT\_p} + \ln \frac{AR}{E} \tag{5}$$

A plot of ln *bT*2*p* against 1000 *Tp* gives a straight line with slope − *ER* .
