I am having issues with modeling an absorption column in COMSOL 3.5a. I have entered the reaction rate (which I am 100% positive is correct), but I am told the units are wrong and cannot run the simulation.

The reaction rate I currently have entered is: -Kya*(c1*8.314*298/101325-Ke*c2*1000/55.55/100^3)

The variables are c1 and c2. COMSOL is telling me I have units of mol/m^3 where mol/m^3*s is required. Since the time is taken care in my constant(s), how do I fix this?
