## Does pH affect rate of diffusion?

The bigger the difference between the two sides of concentration, the faster the molecule will diffuse.

Why does pH affect the rate of diffusion.

The acidity of alkaline properties of the solute can affect the stability of the cell(s).

…

It can occur if there is a concentration gradient, and if the membrane is permeable..

## How do you find the highest rate of diffusion?

As rate of diffusion is inversely proportional to square root of molar mass, Gas with lowest molar mass will have highest rate of diffusion..

## Does size matter in diffusion?

Size and shape also affect the ability of diffusion to supply the demands of the cell. Diffusion is a slow process, particularly within the cytosol. Thus, as cells get larger or more spherical, the average distance matter must travel within the cell increases.

## Why does the rate of diffusion decrease over time?

Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. … Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion. Solvent density: As the density of a solvent increases, the rate of diffusion decreases.

## What are the 4 factors that affect the rate of diffusion?

The rate of diffusion is affected by the concentration gradient, membrane permeability, temperature, and pressure. Diffusion takes place as long as there is a difference between the concentrations of a substance across a barrier.

## How do you determine the rate of diffusion?

Graham’s Law Formula Graham’s law states that the rate of diffusion or effusion of a gas is inversely proportional to the square root of its molar mass. See this law in equation form below. In these equations, r = rate of diffusion or effusion and M = molar mass.

## Which state of matter has the highest rate of diffusion?

gasesRate of diffusion is faster in gas because inter molecular attraction is comparatively less in gases.So they are very free to move as compared to solid materials.

## Which factor does not affect the rate of diffusion?

Of the following factors, the presence of other solutes in a solution does not affect the diffusion of a particular substance or solute. Temperature…

## What makes diffusion faster?

The rate of diffusion depends on three factors: distance – if the diffusion distance is small, diffusion happens faster because the particles do not have as far to travel. … surface area – the larger the surface area the higher the number of particles that will be able to move in a given time so the faster the rate.

## How does size affect the rate of diffusion?

When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective. … this is actually why cells divide.

## What is the rate of diffusion dependent on?

The diffusion rate depends on several factors: the concentration gradient (the increase or decrease in concentration from one point to another); the amount of surface area available for diffusion; and the distance the gas particles must travel.

## Is the rate of diffusion constant?

Since the net movement of diffusing molecules depends on the concentration gradient, the rate of diffusion is directly proportional to the concentration gradient (dC/dx) across the membrane. … P is a constant relating the ease of entry of a molecule into the cell depending on the molecule’s size and lipid solubility.
