Reduced extent equations for chem. kinetics and thermokinetics of consecutive first order reactions have been deduced and math. model for thermokinetics of consecutive first order reactions has been suggested, which can be used to calculate both rate constants and molar enthalpies of two steps simultaneously with thermogram data from a single experiment Thermokinetics of the saponification of di-Et adipate was studied with a conduction calorimeter and the validation of the thermokinetic model in this paper has been verified by the experimental results.

Key words: THERMODYNAMIC PROPERTIES, CALCULATION, REACTION KINETICS, MATHEMATICAL MODELS, ENTHALPY, CALORIMETRY, REACTION RATE CONSTANT, THERMODYNAMICS
