# Relationship between solute concentration and rate of diffusion

### List Some Factors That Would Increase the Rate of Diffusion | Sciencing

the differences in rates of diffusion of different solute particles through a the size of solute molecules and their concentration difference either side of the. The concentration gradient, dC/dx, is the difference in molecule concentration The rate of diffusion will increase with increasing solute concentration, but must. Several factors that affect the rate of diffusion include temperature, density of the diffusing substance, medium of diffusion and concentration gradient. Difference Between Community & Ecosystem The concentration of a substance is defined as the number of solute molecules that can be found within a.

Passive diffusion of solute into a cell is linearly related to the concentration of solute outside the cell. Carrier proteins increase the rate of diffusion by allowing more solute to enter the cell.

Facilitated diffusion, however, approaches a maximum rate as the carrier proteins become saturated with solute. What is the slope of this line? What do increases or decreases in the slope mean biologically?

### How does solute concentration affect diffusion? | Socratic

Now assume the concentration gradient is a constant. Look at the equation for facilitated diffusion and find the horizontal asymptote. Try graphing this equation with different values for K. How does this change the concentration at which the carrier proteins are saturated? Scientific American Books, Inc.

Concentration Difference The rate of diffusion depends on the difference between concentrations across the host material, with higher concentration differences resulting in higher diffusion rates.

## How does solute concentration affect diffusion?

For example, diffusion through a thin wall or membrane will occur quickly if there is a high concentration of the gas on one side and none of the gas on the other side of the wall.

If there is already an almost equal amount of gas on both sides, diffusion will be much slower. Sciencing Video Vault Diffusion Distance The rate of diffusion is inversely related to the distance through which the material is diffusing.

That is, smaller distances result in faster diffusion rates and larger distances result in slower diffusion rates. This makes sense, since a gas diffuses through a thin wall much faster than it would diffuse through a thick wall. Diffusing and Host Materials Diffusion rate also depends on both the material that is diffusing and the material it is diffusing through.

### What is the relationship between diffusion and concentration gradient? | Socratic

At a certain temperature, all particles have the same average energy. This means that lighter atoms, such as hydrogen, carbon, oxygen and nitrogen travel faster and are more mobile than larger atoms such as copper or iron.

Materials made of these lighter atoms diffuse faster than heavier materials. References University of Tennesse, Knoxville:
