Starter track
Follow the authored sequence, or switch to recap mode for a faster review of the same path.
Start with successful collisions setting reaction rate, then reuse the same chemistry language inside a reversible system that re-balances after a disturbance.
Entry diagnostic
Reuse the collision-theory quick test and the equilibrium rebalance challenge to decide whether to start from successful collisions or jump straight into the reversible bench.
Check the chemistry bridge before you skip ahead
No saved diagnostic checks are available yet, so the opening concept is still the best place to start.
Uses the same local-first quick tests, checkpoint challenges, and track history already saved in this browser.
Check whether crowding, heating, barrier-clearing success, and catalyst intuition already stay tied together on the same bench.
No saved quick-test result yet.
Start from a reactant-heavy mixture, choose clearly product-favored conditions, and wait until the forward and reverse rates nearly match again while the mixture stays product-rich.
No saved checkpoint attempt yet.
About this track
Keep the first scan focused on the next lesson. Open the authored rationale and shared-framework notes only when you need them.
Why this order
Reaction Rate / Collision Theory comes first because the forward-versus-successful collision distinction is the clearest foundation for the chemistry slice. Dynamic Equilibrium / Le Chatelier's Principle then reuses that same particle and rate language inside a reversible system, so the later equilibrium shift does not feel like a detached chemistry slogan.
Shared concept pages
Compare mode, prediction mode, quick test, worked examples, guided overlays, challenge mode, and read-next cues stay on the concept pages. The track only decides the guided order and the next recommended stop.
Guided path
Checkpoint cards reuse the authored challenge entries already living on the concept pages.
Keep one chemistry box visible so temperature, concentration, activation threshold, and catalysts can be read as changes in successful collisions instead of chemistry slogans.
Start here before moving into Dynamic Equilibrium / Le Chatelier's Principle.
Build a setup where the reaction is clearly fast even though concentration stays modest. Keep the threshold cue and collision pulses on so you can show that the rate rose because more collisions succeeded.
Finish Reaction Rate / Collision Theory first. This checkpoint ties together Reaction rate through Raise success, not just collision count.
Pause here after Reaction Rate / Collision Theory before moving into Dynamic Equilibrium / Le Chatelier's Principle.
Watch a reversible chemistry bench keep changing microscopically while the mixture settles toward a new balance after each disturbance.
Capstone step after Reaction Rate / Collision Theory.
Start from a reactant-heavy mixture, choose clearly product-favored conditions, and wait until the forward and reverse rates nearly match again while the mixture stays product-rich.
Finish Dynamic Equilibrium / Le Chatelier's Principle first. This checkpoint ties together Reaction rate and Dynamic equilibrium through Create a shift, then let it rebalance.
Final checkpoint that closes the authored track after Dynamic Equilibrium / Le Chatelier's Principle.
