[DELTA][G.sub.b]--Gibbs free energy at isokinetic temperature, kJ [kg.sup.-1]; and,

In order to validate the enthalpy-entropy compensation theory, the Krug test (Eq.9) was applied to compare the isokinetic temperature ([T.sub.B]) with the mean harmonic temperature ([T.sub.hm]), whose approximate confidence interval (1-[alpha]; 100%) for the isokinetic temperature was calculated by Eq.

where: [T.sub.B] = isokinetic temperature (K); and [DELTA][G.sub.B]: Gibbs free energy at isokinetic temperature (kJ [kg.sup.-1]).

The isokinetic temperature is the temperature at which reactions in series occur at the same rate.

Thermodymnamic properties of crambe fruits/Propriedades termodinamicas dos frutos de crambe

The established decrease in the values of [E.sub.a] and lnA under microwave heating compared to the conventional heating permits the possibility of new explanation of the influence of microwave heating on the kinetics of isothermal dehydration based on integration of Larsson model of activating the molecule via selective energy transfer (SET model) [44] and Linert concept of isokinetic temperature [45].

Based on the assumptions above, in accordance with the SET model, considering this resonance system as a classical forced damped harmonic oscillator, it is possible to get the expression for reaction rate constant and isokinetic temperature ([T.sub.ic]):

The effects of microwave heating on the kinetics of isothermal dehydration of equilibrium swollen poly(acrylic-co-methacrylic acid) hydrogel

This indicates the existence of an isokinetic temperature ([T.sub.i]), because in the case of a series of pyrolysis processes there is a temperature [T.sub.i] at which the rate constant exhibits the same value [k.sub.i].

Evaluation of linear kinetic methods from pyrolysis data of Spanish oil shales and coals

The isokinetic temperature has been used to characterize the temperature at which the product is in equilibrium, i.e., when all reactions occur simultaneously (Goneli et al., 2016a).

Hysteresis and thermodynamic properties of water sorption in 'Malagueta' pepper seeds/Histerese e propriedades termodinamicas de sornao de agua em sementes de pimenta malagueta

The isokinetic temperature is the temperature at which the reactions in a series occur at the same rate.

(1976a and b), the linear chemical compensation or compesantion theory exists only if the isokinetic temperature ([T.sub.B]) is different from the harmonic mean of the temperature ([T.sub.hm]).

However, only the difference between the harmonic mean temperature ([T.sub.hm]) and the isokinetic temperature ([T.sub.B]) may indicate that such relationship exists (enthalpy-entropy compensation theory).

Kinetics of water sorption of damaged bean grains: thermodynamic properties/Cinetica de sorcao de agua de graos de feijao danificado: propriedades termodinamicas

Aiming to test the validity of the differential enthalpyentropy compensation theory, isokinetic temperature was compared to the mean harmonic temperature from the temperature range used in this work.
