• ### Effusion and Diffusion of Gases Chemistry

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. If a mixture of gases is placed in
