Solution of the inverse problem in nonisothermal kinetics by a least-squares approach using orthogonal transformations: Solution of the inverse problem in nonisothermal kinetics by a least-squares approach using orthogonal transformations. Poplevin, A. E. (Perm. Gos. Univ., Perm, USSR). Term. 10034-98-7 and 10031-55-7 are cas registry numbers. These chemicals are also mentioned in this article. Anal. Fazovye Ravnovesiya, 7-11. Edited by: Verzhbitskii, F. R. Permsk. Gos. Univ.: Perm, USSR. (Russian) 1985. CODEN: 55VYA5. DOCUMENT TYPE: Conference CA Section: 67 (Catalysis, Reaction Kinetics, and Inorganic Reaction Mechanisms) The inverse problem in nonisothermal kinetics is the fitting of kinetic data to a reaction mechanism so that the activation energy (E), pre-exponential factor (Z), and f(a) (function of the degree of conversion) may be calcd. Solns. of this problem involve transformation of the fundamental kinetic equation da/dt = Z(f(a)) exp(-E/RT). A prior detn. of the form of f(a) is followed by calcn. of Z and E. Exptl. data for thermolysis of rare earth sulfate octahydrates are treated to obtain dehydration kinetic parameters. .
