Thermal decomposition of acetates of potassium, cobalt, zinc, mercury and lead have been investigated using thermogravimetric technique (TGA), under constant flow of nitrogen. The results indicate that major products are acetone, carbon dioxide, oxygen, depending on whether the final solid products is that of oxide or the metal. Kinetic parameters of the thermal decomposition of these metal acetates were investigated on the basis of their respective thermal curves. Calculation of reaction order and an activation energy were carried out by the Coats-Redfern's method and also by Horowitz-Hugh's method giving comparable results.
