“…The time-dependent concentrations of the unreacted energetic material (Figures a−11a), (1 − α), with α (0 ≤ α ≤ 1) representing the reaction progress, were evaluated by implementing Avrami−Erofeyev kinetics
by using the linearized form
We used the Sharp−Hancock plot, − ln(−ln(1 − α)) vs ln( t ), to obtain the reaction exponent m , which is an important indicator of the rate-determining reaction step, and also the reaction rate constant k . The reaction exponent m is the slope, and m ·ln( k ) is the intercept with the ordinate in the Sharp−Hancock plot for the interval α = 0.2−0.63 (see Table 3 of ref ). The time progressions for the runs from Figures a−11a are shown as Sharp−Hancock plots in Figures b−11b, respectively.…”
