In order to examine the applicability of the rectangular pulse technique to the determination of the kinetics of a two-components' reaction on a catalyst in the specified surface state, the kinetics of the reaction of NO with NH/sub 3/ on the V/sub 2/O/sub 5/ catalyst, that is, NO + NH/sub 3/ + VVertical BarO ..-->.. N/sub 2/ + H/sub 2/O + V-OH, has been investigated using the rectangular pulse apparatus. Chromatograms of the individual components have shown that NH/sub 3/ is strongly adsorbed on the catalyst while NO or N/sub 2/ is not or only very weakly adsorbed. The adsorption of NH/sub 3/ has been approximately described by the Langmuir adsorption isotherm. The yield of N/sub 2/ produced by the reaction has changed significantly with the pusle width. This indicates a separation of NO and NH/sub 3/ in the catalyst bed during the pulse experiments. By analyzing the experimental data with the theory of the pulse technique, the kinetics of the above-mentioned two-components' reaction has successfully been determined and it has agreed with the kinetics of the reaction of NO with NH/sub 3/ under excess oxygen conditions determined by using the continuous flow technique. On the basis of these results, the rectangular pulse technique coupled with the theoretical analsysis of the experimental data has been concluded to be a method effective for the determination of the kinetics of a multicomponents' reaction on a catalyst in the specified surface state.
