N2 - Abstract: A brief review of the possibilities of the thermodynamic assessment of the temperature shift of the chemical equilibrium is presented. The contributions of various thermodynamic potentials to the shift values were studied based on the Gibbs–Helmholtz equations. A comparative analysis of the possibilities and necessity of taking into account the temperature changes in the thermodynamic functions was carried out. Systems with synthesis/hydrolysis of esters are considered as examples. © Pleiades Publishing, Ltd. 2024. ISSN 0036-0244, Russian Journal of Physical Chemistry A, 2024, Vol. 98, No. 9, pp. 1981–1990.
