The isotope effects which occur in the reduction of carbon dioxide by zinc were determined. It was shown that in the case of irreversible surface reactions, Bernstein's equation which permits the calculation of the fractionation factor is still valid. These experimental factors are in gocd agreement with those obtained by calculating the partition functions of the adsorbed activated complexes. In the reaction mechanism used, the model of the activated complex corresponds to the dissociation of one of the carbon oxygen bonds CO/sub 2 yields CO + O. Perturbations arising from the slight reversibility of the reaction Zn + CO/sub 2/ in equilibrium ZnO + CO on the isotope effects on the carbon and oxygen atoms were also calculated. (auth)
