Unit error for surface reactions

Please login with a confirmed email address before reporting spam

I want to simulate surface reactions and get an immediate error. Upon creating the reaction, the reaction rate in the Kinetics area gives the message:

"Deduced unit is [mol/m^3], expected is [mol/m^2*s]"

Because of this, it is not possible to make a rough estimation by simply changing the kinetic factor "ksf", or does the model create a solution anyways?

This error is also exists in the "tortuous reactor" model in the library.
