Increase rate of diffusion
Diffusion is a process via which molecules move down a concentration gradient, that is, move from an area of higher concentration (particles per unit volume) to an area of lower concentration. Apart from concentration differences, other factors such as temperature can affect the rate of diffusion. Diffusion occurs when particles move from an area of high concentration to an area of low concentration. The factors affecting rate of diffusion are: concentration, temperature, mass of the particle and properties of the solvent in which diffusion occurs. Faster movement equals faster diffusion. Diffusion is the movement of particles from a high to lower concentration. Osmosis is the diffusion of water across a membrane. Active transport moves particles from low to higher concentration. What Factors Affect the Rate of Diffusion? Credit: Dorling Kindersley/Dorling Kindersley RF/Getty Images. Rate of diffusion is influenced by several factors including temperature, concentration difference and particle size. The diffusion rate is also affected when there is a change in distance between the points where diffusion occurs. Learn the effect that temperature has on the process of diffusion to understand how to speed up the process and how to increase the rate of most chemical reactions. Diffusion is a process by which a concentrated group of molecules gradually becomes less concentrated, either by mixing with nearby molecules or simply by The rate of diffusion of all types is increased along with increasing temperature. Diffusion is really the result of random movements, rather than force, since random movements are more likely to move particles to areas of lower concentration from areas of higher concentration. Diffusion is the movement of particles from an area of high concentration to an area of low concentration. Two laws of diffusion, Graham's law and Fick's law, govern how to calculate the diffusion rate.

When this happens the rate of diffusion also increases, the opposite will happen if the temperature decreases. The Brownian motion of the molecules increases 5 Aug 2012 5. Factors influencing rate of diffusion• Temperature: As temperature increases, the kinetic energy of the particles increases. Thus, the speed of Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Solvent density: As the As temperature increases, the rate of diffusion also increases. Diffusion is a form of passive transport during which particles travel down a concentration gradient. Many factors influence the rate at which diffusion takes place, including the medium through with a substance is diffusing, the size of molecules diffusing, the
The rate of diffusion will increase with increasing solute concentration, but must asymptotically approach the saturation rate, V max. How quick ly the carrier proteins become saturated can be described by the variable K, the concentration gradient at which the rate of diffusion is 1/2 Vmax. K and Vmax depend on properties of the diffusing

Diffusion is a process via which molecules move down a concentration gradient, that is, move from an area of higher concentration (particles per unit volume) to an area of lower concentration. Apart from concentration differences, other factors such as temperature can affect the rate of diffusion.
Diffusion rates are dependent on molecular sizes because larger molecules diffuse slower than smaller molecules. The sizes of the particles involved in the diffusion are important because they closely relate to the concepts of heat and energy in the context of diffusion. In facilitated diffusion, the concentration gradient process is more complex. Increasing the solute's volume once the concentration is high does not alter the rate of diffusion. This is because facilitated diffusion requires carrier proteins, and there is a maximum number (Vmax) present. The variable K influences how fast carrier proteins saturate. Which one of the following would increase the rate of diffusion within a solution? turgor pressure. Cells, when placed in a hypotonic solution tend to swell. Unlike animal cells, plant cells do not rupture due to a cell wall. This type of pressure is known as. hypertonic. The rate of diffusion through a semipermeable membrane will be lowest when temperatures are low. Lower temperatures decrease the energy of the molecules, which in turn decreases the rate of diffusion. The rate of diffusion of all types is increased along with increasing temperature. Diffusion is really the result of random movements, rather than force, since random movements are more likely to move particles to areas of lower concentration from areas of higher concentration.
In this experiment the diffusion of food coloring in hot and cold water shows how temperature effects the rate of diffusion, with the process being much faster in
