Rates and Equilibrium
Not startedStart with successful collisions setting reaction rate, then reuse the same chemistry language inside a reversible system that re-balances after a disturbance.
Use this track when the chemistry pilot should feel like a real branch instead of two isolated pages in the catalog. The path starts with one collision box where temperature, concentration, threshold, and catalysts all stay tied to successful collisions, then carries that particle story into a reversible bench where forward and reverse change compete on the way to a new equilibrium mix.
