Qaisrani M. K. Khan M. Khalid Física, Astronomía y Matemáticas Adsorption mechanism Monte Carlo simulation Heterogeneous catalysis Catalytic surface reactions The effect of experimentally observed hot atom mechanism on the phase diagram using Pt (111) surface ofthe monomer-dimer reaction has been studied. While using this mechanism, whenever O2 molecule hits therandomly vacant selected site, it breaks up into atomic form and then executes ballistic flight. The path of thetwo oxygen atoms is taken exactly opposite to each other i.e. anti-parallel and range of the atoms is takenequal i.e. they may fly upto 1 and 1.73 atomic spacing from the site of impact . Two cases have been studiedon the basis of the range of hot atoms. The steady reactive window is observed and the continuous transitiondisappears. As soon as the CO partial pressure departs from zero the production of CO2is observed, whichclearly verifies the experimental observation. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436208 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.1B Vol.36
