"WebbThe ring usually forms nearer to the hydrochloric acid end of the tube because hydrogen chloride diffuses more slowly than ammonia. This is because hydrogen chloride has almost twice the molecular weight of ammonia, and the rate of diffusion is inversely proportional to the square root of the molecular mass of the gas.

WebbMass 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.

Webb20 nov. 2024 · In gases, diffusion is the fastest, whereas in solids, it is the slowest. Various gases have different diffusion rates. Denser gases intermingle at a slower rate than lighter gases. Dissemination occurs in both liquids and solids. The pace of diffusion in solids, on the other hand, is quite slow. WebbGraham found experimentally that the rate of effusion of a gas is inversely proportional to the square Hot of the molar mass of its particles. [1] This formula is stated as: , where: Rate 1 is the rate of effusion for the first gas. ( volume or number of moles per unit time). Rate 2 is the rate of effusion for the second gas.
