First-order reaction kinetics fitting for the MSC-311⇒MSC-322 transformations. Five identical MSC-311 dispersions in toluene (3 mL) were made from a single MSC-311 sample (~20 mg). The five dispersions were placed at the five temperatures (T) as indicated from 42.5 to 52.5 °C. The time-dependent quantity \({\mathrm{ln}}\left[ {C_{{\mathrm{MSC}} {\mbox{-}} 311}^0/C_{{\mathrm{MSC}} {\mbox{-}} 311}^t} \right]\) (solid circles) fits well with first-order reaction Eq. (3) (solid lines). \(C_{{\mathrm{MSC}} {\mbox{-}} 311}^0\) represents the starting concentration of MSC-311 and \(C_{{\mathrm{MSC}} {\mbox{-}} 311}^t\) is the time-dependent concentration of MSC-311 during the transformation. The slopes of the fitted lines correspond to the rate constants k (min⁻¹). The inset shows the Arrhenius plot, with a y-axis of ln(k) and an x-axis of 1/T. The slope of the fitted line is E_a/R, where E_a is the barrier energy and R the ideal gas constant
