Titration Calorimetry Applied to the Study of Thermokinetics I.Thermokinetics of First-Order Reactions
Abstract:
The mathematical models for thermokinetics of first-order reactions in titration period and in the stopped-titration reaction period have been suggested, respectively, by titration calorimetry. By analyzing the titration calorimetric curve of one experiment of a reaction, these two models can be used to calculate the first-order rate constant (k1) and the molar enthalpy(△rHm) of the reaction. Thermokinetics of the saponification of ethyl acetate in doubly distilled water was studied by titration calorimetry. The reliability of this titration calorimetric method for studying thermokinetics of first-order reactions has been verified by the experimental results obtained.
