Kinetics and stoichiometry of the reaction between ozone and C70 fullerene in CCl4

The kinetics and stoichiometry of the reaction between C-70 fullerene and ozone have been studied. The reaction obeys a bimolecular rate law. The stoichiometric coefficients of the reaction are 1 : 12 to 1 : 22, depending on reaction conditions. The rate constant at 22 degrees C is 5 x 10(4) l mol(-1) s(-1) for the first stage of fullerene conversion and (0.8-0.6) x 10(4) l mol(-1) s(-1) for the subsequent stages. Since the stages differ in terms of reaction rate, the original C-70 molecules are first involved in the reaction, whereas, at the subsequent stages, all molecules are involved with equal probabilities, irrespective of the number of preceding reaction events in which they have participated.
