Arrhenius fit for $k_{\mathrm{p}}$ of DEI. The indicated uncertainties in ln(k_p) result from the standard deviation of the measurements for the respective temperature, while for the uncertainty in T⁻¹ an uncertainty of ΔT = 2 K was assumed. For 30 °C, only one data point exists, consequently the uncertainty in ln(k_p) was assumed to be similar to the other values. The obtained Arrhenius parameters are shown in Table 5.
