What is diffusion rate?
Thereof, what is meant by rate of diffusion?
Definition of Diffusion rate (rate of diffusion) The number of randomly moving molecules that pass through a unit area per second. Diffusion rates are fastest when a large concentration difference exists on either side of the unit area.
Secondly, what is called diffusion? Diffusion is the movement of a fluid from an area of higher concentration to an area of lower concentration. Diffusion may also be thought of as the movement of particles down a concentration gradient. The term "diffusion" comes from the Latin word diffundere, which means "to spread out."
Furthermore, what is rate of diffusion in chemistry?
Graham's law of diffusion (also known as Graham's law of effusion) states that the rate of effusion a gas is inversely proportional to the square root of its molar mass. Often, it is used to compare the effusion rates of two gases.
What is diffusion example?
Diffusion Definition. Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. For instance, a gas diffuses very quickly in another gas. An example of this is the way the noxious smell of ammonia gas spreads in air.
