Journal Article 2024 02 03 In this work, kinetics and thermodynamics of esterification reaction were studied. This research investigated the esterification reaction between methanol and acidified oil catalyzed by sulfonated cation exchange resin and proposed a new rate equation for consideration of kinetics of this reaction according to the Langmuir-Hinshelwood mechanism. Thermodynamics and kinetics parameters were calculated according to this equation. The results of this study showed that this new equation was a reasonable equation for kinetics study of the esterification reaction. Also, kinetics parameters were calculated for this reaction. Activation energy and Arrhenius pre-exponential factor were equal to  and  respectively.
