ANÁLISIS DE LA TASA DE REACCIÓN EN SISTEMAS MULTICOMPONENTES REACTIVOS EN CINÉTICA QUÍMICA

Abstract

Reactive transport processes are defined by two processes: the transport of hydrodynamic solutes defined by the advectivo flow and the dispersive flow, and chemical reactions between involved species. When the reactions present in the processes of water flow analyses kinetic chemistry (reactions slow), the rate of reaction that describes this phenomenon can be modeling through a nonlinear partial differential equation and no homogeneous which has no exact solution due to the complexity of their terms. This research presents a numerical approximation of that equation give an explicit scheme by the method of finite differences, concluding that if reaction times are greater than the characteristic times of transport, chemical reactions are much more representative of the change in the concentration of species.
