Rate laws ammonia oxidation

Ostwald process The production of nitric acid by the catalytic oxidation of ammonia, overall order The sum of the powers to which individual concentrations are raised in the rate law of a reaction. Example If the rate = [S02][S03]" l/2, then the overall order is f. 

Clerici cites considerable support for the mechanism involving the Ti (q -OOH) species [373]. In TS-1, numerous spectroscopic studies [412] show the adsorption of protic molecules on Ti sites, for example, as observed by XANES by the decrease in intensity of the tetrahedral Ti pre-edge peak on adsorption of water and ammonia [413]. Rate laws suggest that one molecule of alcohol solvent is adsorbed on the active species in the oxidation of alcohols [414] and the... 

Ostwald process an industrial preparation of nitric acid starting from the catalytic oxidation of ammonia to nitric oxide. (22.7) Overall order of a reaction the sum of the orders of the reactant species in the rate law. (14.3)... 

There have been some recent investigations of photoelectron injection into electrolytes which examine the fate and energetics of the solvated electron in liquid ammonia, rather than the process rate laws. Vondrak and coworkers have proposed a procedure to estimate the effective threshold energy from the integral current produced by white light versus 1/T. The method was tested with oxidized W, Na ,W03, and TiO electrodes. 

Isotopic experiments on a Ba-Na-Y zeolite catalyst [15] have shown that the formation of N2 takes one nitrogen atom from NOx and another nitrogen atom from ammonia. One important reaction for ammonia-SCR over Fe-zeolite is the NO oxidation to NO2, because the presence of NO2 can significantly improve the SCR performance, especially at low temperature [25, 39 1]. The reaction rate of the ammonia-SCR can be described by the following simple power law ...
