Effusion and Diffusion of Gases – Chemistry 2e

(a) Two gases, H 2 and O 2, are initially separated.(b) When the stopcock is opened, they mix together. The lighter gas, H 2, passes through the opening faster than O 2, so just after the stopcock is opened, more H 2 molecules move to the O 2 side than O 2 molecules move to the H 2 side. (c) After a short time, both the slower-moving O 2 molecules and the faster-moving H 2 molecules have ...
