Looking at Table , it is notable that the ring opening product (2) is not thermodynamically favourable for the investigated reaction across the entire temperature range (300-1000 K), while both ring contraction and dehydration mechanisms are favourable. Interestingly, the dehydration product, D7 + H 2 O, is unfavourable at 300 and 400 K, but becomes favourable at 500 K. The rate coefficients were calculated within the temperature range of 300 to 1000 K using reaction barriers computed at the junChS level of theory (refer to Table ). The temperature dependence rate constants plot is presented in Figure . As previously noted in the literature , ring opening is the fastest reaction channel throughout the entire temperature range. The other reaction channels are slower by 1-2 orders of magnitude, which means that, kinetically, ring opening is always favourable. The Arrhenius plots indicate that the investigated reactions follow the expected Arrhenius behavior within the temperature range studied. However, for dehydration reactions involving TS-D4, TS-D5, and TS-D6, there are slight deviations from the trend at lower temperatures.
