摘要：

Kinetic constants and activation parameters of some inorganic reactions in solution have been obtained very easily and with great accuracy from variable temperature spectrophotometric kinetic data using a method based on non-isothermal analysis. The reactions studied under various experimental conditions to test the method were the cis-trans isomerization of the cation [Pt(PEt3)2(CH3)(C2H5OH)]+ in ethanol and the thermal decomposition of the alkyl solvent species trans-[Pt(PEt3)2(n-C4H9)(CH3OH)]+ to yield the trans-hydride [Pt(PEt3)2(H)(CH3OH)]+ in methanol. The results are compared with those obtained by the traditional isothermal method. A suitable experimental apparatus and software is described for routine measurements.
