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. WebOct 27, 2024 · Applying Graham’s Law to Rates of Effusion Calculate the ratio of the rate of effusion of hydrogen to the rate of effusion of oxygen. Solution From Graham’s law, we have: rate of effusion of hydrogen rate of effusion of oxygen = 32 g mol −1 2 g mol −1 = 16 1 = 4 1 Hydrogen effuses four times as rapidly as oxygen.
