The Quantitative Kinetic Molecular Model and Effusion/Diffus
Effusion was explained by a Scottish chemist named Thomas Graham. Thomas Graham found experimentally that the rate of effusion of a gas is inversely proportional to the square root of the mass of its particles. The equations of Graham’s law of effusion, is square root of the molar mass of gas one over the square root of the molar mass of gas two.
Diffusion is the effusion into a closed area of space. Diffusion is experimentally impossible to calculate with today’s technology. We can, however, calculate the diffusion rate in a vacuum by using Graham’s law of effusion. Using the ratio created
