This research presents a numerical solution of the multicomponent reactive transport problem in a two-dimensional saturated porous media under steady flow conditions. The solved problem is a system with two simultaneous reactions, one instantaneous and another slow relative to the groundwater flow and the physical processes of solute transport, assuming that the aquifer is physically homogeneous and does not exhibit any temporal or spatial variations in temperature. Based on the methodology proposed by Molins et al. [1] and developed by Donado et al. (submitted to Water Resour. Res.) [2], the reactive transport system is decoupled into two components, one for each reaction (equilibrium and kinetic). Thus, the conservative component represents the equilibrium reaction and the kinetic component the slow reaction. This way the multicomponent reactive system is reduced to the solution of two partial differential equations. The main outcome of this research is that the equilibrium reaction rate can be defined as a function of the mixing and the kinetic reaction rate. [ABSTRACT FROM AUTHOR]
