Reversible reaction

Reaction that can proceed in both directions

Chemical system

Chemicals actively participating in the reaction

Closed system

System where no matter can enter or leave

Open system

System allowing substances to be added or removed

Physical change

Change in form/state without creating new substances

Chemical change

Reactants produce new substances with different properties

Dynamic equilibrium

Forward and reverse reactions occur continuously

Symbol for reversible reaction

Double arrow (\rightleftharpoons)

Activation energy (EaE_a)

Minimum energy required to break bonds in reactants

Requirement for reversibility

Both forward & reverse reactions need low activation energy
