n. pl. e·qui·lib·ri·ums or e·qui·lib·ri·a (-rē-ə)
1. A condition in which all acting influences are canceled by others, resulting in a stable, balanced, or unchanging system.
2. Mental or emotional balance.
3. Physics The state of a body or physical system at rest or in unaccelerated motion in which the resultant of all forces acting on it is zero and the sum of all torques about any axis is zero.
a. The state of a chemical reaction in which its forward and reverse reactions occur at equal rates so that the concentration of the reactants and products does not change with time.
b. The state of a system in which more than one phase exists and exchange between phases occurs at equal rates so that there is no net change in the composition of the system.
[Latin aequilībrium : aequi-, equi- + lībra, balance.]
n, pl -riums or -ria (-rɪə)
1. a stable condition in which forces cancel one another
2. a state or feeling of mental balance; composure
3. (General Physics) any unchanging condition or state of a body, system, etc, resulting from the balance or cancelling out of the influences or processes to which it is subjected. See thermodynamic equilibrium
4. (General Physics) physics a state of rest or uniform motion in which there is no resultant force on a body
5. (Chemistry) chem the condition existing when a chemical reaction and its reverse reaction take place at equal rates
6. (General Physics) physics the condition of a system that has its total energy distributed among its component parts in the statistically most probable manner
7. (Physiology) physiol a state of bodily balance, maintained primarily by special receptors in the inner ear
8. (Economics) the economic condition in which there is neither excess demand nor excess supply in a market
[C17: from Latin aequilībrium, from aequi- equi- + lībra pound, balance]
e•qui•lib•ri•um(ˌi kwəˈlɪb ri əm, ˌɛk wə-)
n., pl. -ri•ums, -ri•a (-ri ə)
1. a state of rest or balance due to the equal action of opposing forces.
2. equal balance between any powers, influences, etc.; equality of effect.
3. mental or emotional balance; equanimity.
4. a state or sense of steadiness and proper orientation of the body.
5. the condition existing when a chemical reaction and its reverse reaction proceed at equal rates.
[1600–10; < Latin aequilībrium=aequi- equi- + lībr(a) balance]
e•quil′i•bra•to`ry (ɪˈkwɪl ə brəˌtɔr i, -ˌtoʊr i) adj.
1. Physics The state of a body or physical system that is at rest or in constant and unchanging motion. The sum of all forces acting on a body that is in equilibrium is zero (because opposing forces balance each other). A system that is in equilibrium shows no tendency to alter over time.
2. Chemistry The state of a reversible chemical reaction in which its forward and reverse reactions occur at equal rates so that the concentration of the reactants and products remains the same.
The state of a reversible chemical reaction at which the forward and backward reactions take place at the same rate

|Noun||1.||equilibrium - a stable situation in which forces cancel one another|
situation, state of affairs - the general state of things; the combination of circumstances at a given time; "the present international situation is dangerous"; "wondered how such a state of affairs had come about"; "eternal truths will be neither true nor eternal unless they have fresh meaning for every new social situation"- Franklin D.Roosevelt
