• Anomalous behavior of heterogeneously catalyzed CO oxidation on ZnO at the steady state and the transient state has been interpreted by the multi-reaction pathway model based on the different intermediates (Is).The reaction mechanism consists of a Langmuir-Hinshelwood(L-H)part，in which Is O(neutrally adsorbed oxygen)，and an Eley-Rideal(E-R) part with O^-. The mode of transient response curve is sensitively shifted among a monotonous，an overshoot， a false start and a complex type according to the concentrations of CO and O_2. The proposed model consistently explains the anomalous steady state rate kinetics and the mode of transient response curves，and all the kinetic parameters of the reaction sequences are evaluated by using a computer simulation technique，indicating the good fit to the experimental curves.
