## What stops the process of diffusion?

The process of diffusion usually stops when the concentration of the substance is at equilibrium. In other words, there is no movement in one direction.

## Does the diffusion eventually come to an end Why?

it is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration. Diffusion will continue until the concentration gradient has been eliminated.

Does diffusion continue until solutions are in equilibrium?

Because diffusion depends upon random particle movements, substances diffuse across membranes without requiring the cell to use energy. Even when equilibrium is reached, particles of a solution will continue to move across the membrane in both directions.

How long does the process of diffusion continue for?

Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. The difference in the concentrations of the molecules in the two areas is called the concentration gradient. Diffusion will continue until this gradient has been eliminated.

### Can diffusion stop?

Diffusion stops when the concentration of the substance is equal in both areas. This does not mean that the molecules of substance are not moving any more, just that there is no overall movement in one direction. Molecules of substance are moving equally in both directions.

### When diffusion stops we say the solution has reached?

Diffusion stops when the particles are spread out evenly. The particles are still in constant motion, but because there is no concentration gradient, the solution has reached equilibrium. DIRECTIONS: 1.

Will diffusion ever stop completely?

Diffusion will continue until the concentration gradient has been eliminated. Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes “down the concentration gradient”.

Do molecules ever stop moving?

The quick answer to your question is no, molecules do not stop moving at absolute zero. They move much less than at higher temperatures, but they still have small vibrations at absolute zero.

## When equilibrium is reached during diffusion particles stay still and will not move?

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.

## Does osmosis ever stop?

If the membrane is highly permeable to solute as well as to water, no water flow will occur and, therefore, the externally applied pressure required to stop osmosis is zero.

When the process of diffusion reaches an equilibrium state?

1 Answer. Ernest Z. Equilibrium is reached when there is a uniform distribution of solvent particles or when there is an equal concentration of solute on each side of a membrane.
