WebFigure 9.6.2. 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. WebJun 25, 2024 · 23K views 3 years ago We know that molecules will travel at an average velocity that is inversely proportional to their molar mass. This means that lighter gases travel faster. We can relate the...

Previous Section Standard Temperature and … WebGraham's law of effusion (also called Graham's law of diffusion) was formulated by Scottish physical chemist Thomas Graham in 1848. Graham found experimentally that the rate of effusion of a gas is inversely proportional to the square root of the molar mass of its particles. This formula is stated as: =, where: Rate 1 is the rate of effusion for the first gas.
