KINETICS OF NONISOTHERMAL DECOMPOSITION OF [CO(NH3)5X]BR2 COMPLEXES WITH X=CL, BR OR I ATOMS

The mechanisms of the non-isothermal decomposition of [Co(NH3)5X]Br2 c omplexes with X = Cl, Br or I atoms are reported together with the det ermination of the kinetic parameters Z, E, DELTA(H) and DELTA(S) by no n-isothermal methods. The complexes decomposed in well defined steps a nd the mechanisms by which decomposition took place have been manifest ed. The TG, DTG and DSC of the various complexes were taken under N2 a s well as O2 atmosphere. The enhancement effect of O2 gas on the decom position steps has been interpreted.
