Webaverage kinetic energies of the molecules of different gases are equal. Graham’s Law of Diffusion is based on the above assumptions of Kinetic Molecular Theory. The theory can be stated in the following form: The rates of diffusion of different gases are inversely proportional to the square roots of their molar masses. × 5 × 6 = § Ú Ô à 6

Of hydrogen the specific gravity is 0.0694 (air= 1), of which num- ber the square root is 0.2635. Now, according to our law, 1 volume hydrogen should be replaced by 0.2635 air. fish pingu

WebMar 16, 2024 · Graham's law of diffusion, also known as Graham's law of effusion, states that the rate of diffusion or effusion of a gas is inversely proportional to the square root of its molecular weight. According to Graham's law, lighter gases diffuse or effuse quickly than heavier gases at the same temperature and pressure. WebFigure 2. Diffusion occurs when gas molecules disperse throughout a container. Effusion occurs when a gas passes through an opening that is smaller than the mean free path of the particles, that is, the average distance traveled between collisions. Effectively, this means that only one particle passes through at a time. WebThe rates of effusion of gases are inversely proportional to the square roots of their densities or to the square roots of their atoms/molecules’ masses (Graham’s law). The concentration of a gaseous solute in a solution is proportional to the partial pressure of the gas to which the solution is exposed, a relation known as Henry’s law. fish pink floyd
