Transport phenomena and chemical reaction rates are influenced by temperature. This effect is reflected on the numerical value of the coefficient rate, which therefore depends on the variable temperature. Both for mass transfer coefficient and chemical reaction coefficient, various theoretical approaches have been suggested in order to predict and quantify their dependency on the temperature. However, these approaches have had limited success, and the effect of the temperature is generally obtained through experimental evidence. A generally accepted relationship linking kinetic coefficient and temperature is the Arrhenius’ law, which is written as
$$ k={k}_0 \exp \left(-\frac{E}{RT}\right) $$
