Rubidium soaps (Caprylate, Myristate and Pamitate) were analyzed thermally using TGA Technique and thermo grams were obtained to determine their energy of activation. These soaps show single step thermal degradation. The TGA data have been investigated in terms of Freeman andcarroll equation. Coats-Redfern, Horowitz-Metzger equations have also been applied successfully to evaluate the energy of activation. The process of decomposition reaction is kinetically of zero order and energy of activation for these soaps liein the range 5.4-5.6 Kcal mol-1
