As a reaction rate function I selected the Arrhenius one and then I properly inserted the pre-exponential factor, activation energy and so on.nnThen, when I run the simulation I see that no products are formed and it seems that the reaction is actually not occurring. I don't think it is a matter of letting the simulation run, because I tried with arbitrary and very high factors of the Arrhenius law and the behavious remained identical.nnI do not understand where is my issue. Maybe I need to define a mass transfer mechanism with the heterogeneous reaction rate in order to see the formation of the products...nnThank your for your attentionn
