Abstract: On the theoritical basis of thermokinetics proposed in previous articles, the thermokinetics for saponification of the ethyl esters of acetic, propionic, and normal butyric acids have been studied at 20 and 30 ℃ in 85% ethyl alcohol aqueous solution with the method of dimensionless parameter for the first order reactions. The rate canstants and the activation energies of these reactions are in reasonable agreement with the values in literature. The activation free-energies of the reaction have been calculated.
The studied region for initial concentration of reactant and rate constant of reaction limited by cooling constant of calorimeter has also been discussed in this paper.
