Yes, now I see this. So, maybe mathematically I have setup the problem
incorrectly. I would like to allow the concentrations at the interface to
increase if the rate of back diffusion becomes greater than the rate of decay.
The rate of decay at the interface is dc/dt = -kt.

To estimate back diffusion and an accumulation at the interface (left-most
boundary), don't I want the precursor of the exponential to change at every
timestep as phi changes?
Forgive me if this should be evident, but want to make sure I understand.
Again, thank you for your assista

I don't know whether the following is the solution you want
