what is the definition of equilibrium?

1.) 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: The pressures of the situation caused her to lose her equilibrium

4.) Chemistry. the condition existing when a chemical reaction and its reverse reaction proceed at equal rates

-OR-

Lower on the list of definitions;

A sensory system located in structures of the inner ear that registers the orientation of the head

Yes equilibrium refers to the balance of particles-molecules or solutes or water on either side of the cell membrane. We have to qualify this by stating that the membrane has to be permeable to the particle that is to be considered in balance or equilibrium. Remember too, that the particles are always in motion so a better reference would be that the substance is in dynamic equilibrium on both sides of the membrane since the particles are free to move through the membrane then they will end up being in even concentration on both sides of the membrane.

Ok, I take chem 1 and 2 so we just went over this, equilibrium is when two substances are at a state of being balanced. When a substance *chemical, or organism* are at equilibrium they are balanced or in equal proportion. Take for example, if i combined equal amounts of hydrogen and chlorine they would form HCl (hydro chloric acid) at equilibrium. If I added to much hydrogen then there would be a nasty reaction and the two substances would no longer be situated at equilibrium. Hope that helps!

Balance, Posture

In chemical equations it refers to a reversible type of reaction, or that some amount of the product simultaneously changes to reactants.

a static or dynamic state in which all forces or processes are in balance and there is no resultant change

chemistry state of balance in chemical reaction: the state in a reversible chemical reaction in which the reaction and its reverse reaction proceed at the same rate and balance each other so there is no further change

Equilibrium is the condition of a system in which competing influences are balanced.

All things being equal during change

eqilibrium is a stable situation in which forces cancel one another
