- Mechanical equilibrium: A system is in mechanical equilibrium when there is no unbalanced force or pressure difference acting on/within it — the pressure is the same throughout the system and equals that of the surroundings, so there is no net motion or tendency toward one.
- Chemical equilibrium: A system is in chemical equilibrium when its chemical composition is uniform throughout and does not change with time — there is no net chemical reaction taking place and no net diffusion of matter from one part of the system (or between system and surroundings) to another. …
