"Some idea of mechanics" hahahha... you might say that.... 4th year Mech eng... yeah, we get a bit of that kinda stuff....
anyhow, the reaction force on the block experience during acceleration is known as Inertia, basically the blocks desire to stay still. on top of this you have a building resistance caused by things like friction between the block and the surface as well as air friction, once the applied force equals the resistance forces we have equilibrium once again, at this time inertia = 0.
and please note, like i said earlier 99% of laws etc rely on the system being in equilibrium, while a system is unbalanced then your friction forces don't have a single number to represent them, all reaction forces need equations for representation. i have no idea what your background of physics/mechanics is, but newtons 1 and 3 rely on the system being in equilibruim,
2 is really the key to this argument in a way... F=MA. since M (mass) is constant, you need F (force) to get A (accelleration). however as we mentioned before you have the forces I (inertia)......... *thinking thinking*
hmmm... perhaps you could say that the opposite force during accelleration IS inertia, but then the point with that i fail to see is this inertia would then make the system of forces balanced... therefore we'd have no accelleration
