Due to the high interest in the chemistry of subcritical systems, kinetic rates of many liquid phase reactions have been measured and investigated under subcritical conditions. They are typically measured at multiple temperatures under constant pressure and fitted to the Arrhenius equation, which can then be used to estimate rate constants at different temperatures. The Arrhenius equation is the most widely used functional form for describing the temperature (𝑇 ) dependence of a rate constant (𝑘) and has a following form:
