ijms-16-01711-f005: FWO diagram, for SB2 derivative.

Mentions: According to this equation, for constant value of α of each different β, the value of activation energy (Ea) could be calculated using the linearity between ln β and reciprocal of temperature (T−1). Therefore, the calculated activation energy values (Ea) can be obtained through Equation (5) using the slope value of straight lines, nearly parallel, for all the conversion degree, which are presented in Figure 4 and Figure 5.
