Conductometric measurement technique has been deployed to study kinetic of depolymerization of polyethylene terephthalate (PET) and NaOH using cobalt acetate and manganese acetate catalyst. Chemical kinetic of this reaction shows second order kinetics. The specific reaction rate without catalyst is 2.88 X 10^-3g^-1 s^-1 at 70^oC. Specific reaction rates were determined at various temperatures ranging from 50^oC to 80^oC. From the data, Arrhenious constant, energy of activation were determined and found to be 5.0 X 10⁶min^-1 and 54.2 KJg^-1 respectively. Similarly the activation parameters were determined using cobalt acetate and manganse acetate as catalyst.
