comsol Nernst-Planck application mode

Please login with a confirmed email address before reporting spam

I have difficluty in dealing with the source term for the Nernst-Planck equation. The reaction can be safely assumed as at equilibirum and I have equilibrium constant only for each reaction. But I do not have kinetic constant for each reaction. How can I integrate equilibirum reactions into nerst-Planck applciation mode? Do I need to get the reaction engineering lab?

Thanks.

I am also trying to add spatially dependent equilibrium reactions to a transport problem. It appears that comsol only supports equilibrium reactions in CSTR, Batch, etc mode. Is there any way to work around this...

Thanks for the help,
