WebJun 1, 2024 · The Gray-Scott model describes the following chemical transformations: (5) A+2B→3B (6) B→C where C is an inert substance. Equations describing the concentrations of substances A and B: δ a δ t = D a δ 2 a δ x 2 − a ∗ b 2 + F − F ∗ a (7) δ a δ t = D b δ 2 b δ x 2 + a ∗ b 2 − ( F + K ) ∗ b where D a , D b are the ... WebFeb 1, 2004 · To reduce the problem for a detailed study, Gray and Scott focused on a model with the overall stoichiometry: A→B, using the reaction rate law: ka (a= [A]). When the reaction is catalyzed by some species Y (the catalyst): A+Y→B+Y, the reaction rate is kay. Our focus is on cubic autocatalysis: A+2B→3B, with rate= kab2.
