Diffusion and Effusion

Diffusion and Effusion. The rates of diffusion and effusion depend on the relative velocities of the gas molecules. The faster the gas molecules are moving, the faster they diffuse/effuse. At the same temperature, molecules with a lower mass move faster than molecules with a higher mass.
