The dependence of conversion degree estimated from the (TG) curve of the mass loss on heating of temperature has been analyzed.
It has been shown that dynamic TG curve can be modeled by an equation relating to the logarithm of conversion degree as a
function of temperature. A coefficient in the equation developed provides information on the distance from the equilibrium,
therefore, the coefficient a2=0–50 implies equilibrium, while a2>50 informs about some distance from the equilibrium. Further possibilities for the use of the models of lnα vs. 1/T in the analyses of thermodynamics and kinetics of thermal dissociation of solids has been shown.
