The diffusion of a gas is faster than the effusion of a gas.

Question

Quizplus · Accepted Answer

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration, while effusion is the process by which gas molecules pass through a tiny opening from an area of high pressure to an area of lower pressure. The rate of effusion is generally faster than diffusion because effusion involves movement through a small opening, which can occur more rapidly than the spreading out of gas molecules in diffusion.
