Dear Ethan, I perhaps shall add that time for molecule to transition between two neighboring compartments is equal to 1/ktr, therefore total time for molecule to reach the absorption site will be sum of times for n+1 compartments, e.g. (n+1/ktr). Rada

You will notice that the part of analytical solution is factorial function (n!). If the chain had a length of n transit compartments, one would need to use factorial for (n-1). This would require bounding of initial conditions for n (lower boundary at 1). Whichever approach you use, the outcome shall be the same. Clearly, our preferred approach is the one we published.

I could not understand why the relationship between mean transit time and transit rate is MTT=(n+1)/Ktr. Could someone help me understand? Thank you.
