For the most common kinetic models used in heterogeneous reactions, the dependencies on xm = E/RTm (E is the activation energy, Tm is the temperature corresponding to maximum process rate, R is the gas constant) on the relative errors (e%) in the determination of the activation energy from the slope of the Kissinger straight line ln(β / Tm2) vs. 1/Tm (β is the heating rate) are evaluated. It is pointed out that, for xm≥10.7 and all kinetic models, ∣e%∣≤5%. Some possible cases exhibiting high values of ∣e%∣, which can be higher than 10%, are put in evidence and discussed.
