Fig. 6 presents the Arrhenius plot for a temperature range of 348.15 K to 393.15 K. To determine the unknown parameters k0 and EA a least square regression of the fitted reaction rate constants were performed. The pre-exponential factor is determined as k0 = 4.72 × 102 m3 mol−1 s−1 and the activation energy is EA = 36.62 kJ mol−1 .
