ABSTRACT:

The uncatalysed thermal decomposition of potassium peroxydisulphate was studied titremetrically. The study showed that the decomposition follows a first order kinetics. Thermodynamic parameters, activation energy (DEa) , frequency factor (A), entropy change (DS) and the free energy change (DG) of the thermal decomposition were evaluated from the values of the first order rate constants KO at different temperatures.
