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.

Keywords

Arrhenius integral, Kinetics reaction, Non-isothermal kinetic, Incomplete gamma function
