New approximate formula for the arrhenius temperature integral by using incomplete gamma functions
Abstract
A new analytical formula for the Arrhenius integral has been proposed by using incomplete gamma
functions, which is simple, accurate and reliable. The proposed formula has compared with several
published the Arrhenius integral approaches, and is in agreement with the other approaches. Compared
with the other approximate formulas proposed in the literature, our proposed method gives more accurate
values in the precision of the activation energy as a function of x and temperature.
