Particles are spread equally and continue to move but with 0 net movement.

Detailed explanation-1: -Even when equilibrium is reached, particles do not stop moving across the cell membrane. Although it may seem as if the concentrations are not changing, nearly equal numbers of particles cross the membrane in both directions. This means that there is no net change in the concentration of the substances.
Detailed explanation-2: -At equilibrium, movement of molecules does not stop. At equilibrium, there is equal movement of materials in both directions.
Detailed explanation-3: -As a system approaches equilibrium, both the forward and reverse reactions are occurring. At equilibrium, the forward and reverse reactions are proceeding at the same rate. Once equilibrium is achieved, the amount of each reactant and product remains constant.
Detailed explanation-4: -Excytosis A state reached when particles continue to move but in equal amounts in and out of the cell.
Detailed explanation-5: -Simple diffusion stops when equilibrium is reached. This means that diffusion will only occur while there is an area where the substance is more highly concentrated. Once both sides of the membrane have an equal concentration of the substance, diffusion will stop.
