1. Why is there a definite sublimation temperature T?
The idea only works at constant /pressure/, with the solid
nearly in equilibrium with its vapor.
With that added requirement, the explanation is pretty simple.
All physics is /locall/. Look at what is going on locally at
the surface. The surface doesn't know how much solid is
behind it or how much vapor is in front of it; all it knows
is the local temperature, pressure, density, et cetera.
None of that changes as the reaction progresses.
