Diffusion Coefficient
</dt>
The absolute value of the ratio of the molecular
flux per unit area to the concentration gradient of a gas diffusing
through a gas or a porous medium where the molecular flux is evaluated across
a surface perpendicular to the direction of the concentration gradient. See diffusion, coefficient
of mutual diffusion.
