Good Day All.
I am working on a simlation of gases reactiing underground and i am trying to use the Chemistry interface together with the Transport of concentrated species to simulate the gas flow and reactions. For the reaction i would like to use thje Arrhenius expression to define kf. From literature i have values for the A factor and EA but i am not sure about the n factor that comsol asks for if you select " Use Arrhenius eq" thus i would like to define kf using the Arrhenius formula in the forward rate constant box. i inputted A2sexp(-EA5/Rht.T) where A2 is the Pre exponent i got from literature (mol/ m3*s) EA activation energy i also defined from literature ht.T was defined to derive the temperature from the Heat transfer interface i am also using . When using this formula i realized eventually that even though Comsol is showing no errors with the expression my reaction is not proceeding. I am at a loss why it is not so was wondering if a more keen eye can assist me in identifying the problem. Any assistance would be greatly appreciated
Regards
