Kinetics
Measure how quickly a reaction changes and what controls its pace.

Concentrations set encounter rates. Particles must meet, orient, and have enough energy for a productive event.

The order changes how concentration enters the rate law. A first-order half-life is independent of starting concentration in the ideal model.
The curves are relative concentration traces. A measured rate law must be inferred from data; stoichiometric coefficients do not automatically become reaction orders.
