Conceptual model of parallel heterogeneous reactions in the presence of three minerals (\(M_a, M_b\), and \(M_c\)) in discretized time t and space x for a finite difference approach. At each grid point, a set of partial differential equations conserving the masses of the chemical components in the system is solved, considering diffusion and heterogeneous reactions.y Heterogeneous mineral-water reactions are included in the model by using reaction rates that depend on the solution composition at each x and t (\(C_{x,t}\)). Active reaction pathways are determined from the local variable \(C_{x,t}\). At the observable time \(t = T\), the type and amount of mineral present varies with x because the reaction pathways differ according to \(C_{x,t}\)
