What affects the rate of diffusion the most?
The greater the difference in concentration, the quicker the rate of diffusion. The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.
What is the exact relationship between the rate of diffusion of a gas and its density?
The relation between its density and the rate of diffusion of a gas can be represented by Graham’s law which states that “The rate of diffusion of a gas is inversely proportional to the square root of its density under given conditions of temperature and pressure.”
How does density affect effusion rate?
Graham’s law states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight. Therefore, the rates of diffusion of different gases are inversely proportional to the square roots of their mass densities.
What is the relationship between density of the medium and diffusion rate?
Solvent density: As the density of a solvent increases, the rate of diffusion decreases. The molecules slow down because they have a more difficult time getting through the denser medium. If the medium is less dense, diffusion increases.
How does size affect the rate of diffusion?
Explanation: 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.
How can density be used to determine the rate of diffusion?
Effusion of a gas is its passage through a pinhole or orifice. Graham’s Law of Diffusion: the rate of diffusion of one gas through another is inversely proportional to the square root of the density of the gas….Key Concepts.
| rate of diffusion | ∝ | 1 √density |
|---|---|---|
| rate of diffusion | = constant × | 1 √density |
How does molecular weight affect diffusion?
Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. The reverse is true for lighter molecules. Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion.
What would be the effect of density of liquids on the rate of diffusion of liquids?
The increase in density will decrease the rate of diffusion. On increasing the temperature, the diffusion increases and on increasing the density of substance, the diffusion decreases and vice versa.
What are the 3 factors that affect the rate of diffusion?
Several factors affect the rate of diffusion of a solute including the mass of the solute, the temperature of the environment, the solvent density, and the distance traveled.
Who established the relationship between density and rate of diffusion of a gas?
Graham’s Law of Diffusion: the rate of diffusion of one gas through another is inversely proportional to the square root of the density of the gas. Graham’s Law of Effusion: the rate of effusion of a gas is inversely proportional to the square root of the density of the gas.
