The kinetic behavior of the thermal decomposition of synthetic malachite wa
s investigated by means of CRTA under different conditions of reduced press
ure, flowing gases and quasi-isobaric atmospheres. The thermal decompositio
n was found to proceed at lower temperatures under the influence of the sel
f-generated gases, CO2 and H2O. From a viewpoint of chemical equilibrium, t
he normal and opposite effects on the overall kinetics were observed for th
e self-generated CO2 and H2O, respectively. The complexity of the present r
eaction is also reflected by the variations of the apparent kinetic paramet
ers which depend on the applied and self-generated atmospheric conditions.
The practical usefulness of CRTA when applied to a complicated thermal deco
mposition is discussed as exemplified by the kinetic approaches to the pres
ent reaction.
