The kinetics of the decomposition of N2O on a catalytic surface is simulated by means of the Monte Carlo technique. The results show that the reaction rate is dependent not only to the mole fraction of N2O in gas phase, but also to the surface-O coverage. The surface-O coverage increases with the increasing of the mole fraction of N2O in gas. When the reaction gas is pure N2O, the surface-O coverage can be a constant, and it is independent to the pressure of N2O gas.

Key words: Monte Carlo method, N2O decomposition, Surface coverage
