Reaction Rates and Equilibrium

Flashcards covering vocabulary terms related to reaction rates and equilibrium.

Reaction Rate

The rate at which reactants change into products.

Collision Model

States that atoms, ions, and molecules must collide in order to react.

Catalyst

A substance that speeds up a chemical reaction without being permanently changed itself.

Inhibitor

A substance that slows down reactions or prevent them from occurring without being changed in the reaction itself.

Reversible Reaction

A reaction that can occur in both forward and reverse directions.

Equilibrium

A state in which forward and reverse reactions or processes proceed at equal rates.

Le Châtelier's Principle

If a stress is applied to a system at equilibrium, the equilibrium shifts in the direction that opposes the stress.
