Graham's law of diffusion experiment
WebGraham’s Law of Diffusion is based on the above assumptions of Kinetic Molecular Theory. The theory can be ... In an experiment similar to the one which you performed, substance X was substituted for HCl. Ammonia was found to have a diffusion rate of 5.0 cm/minute, and substance X at a rate of 4.6 cm/minute. ... WebThis formulation follows from Graham's observations and the facts that the rate of diffusion (or effusion) is directly proportional to the volume of gas diffused (or effused) in a given time and that the density of a gas is proportional to its molar mass. Note: Diffusion and effusion are distinct but related phenomena of molecular transport.
