What 2 external factors speed up diffusion? What is Dynamic equilibrium?

Answer 1

diffusion is basically two or more things mixing between each other. Surface area and temperature are the 2 external factors that affect diffusion.

Dynamic equilibrium is when there are lots of changes going on in a system, but the net change is 0. For example, if the US population remained constant it would be in dynamic equilibrium since lots of people are constantyl dying/being born but the net effect is 0.

Answer 2

In general terms, diffusion occurs at a rate that is proportional to a diffusion constant times the gradient of whatever is being diffused. In real terms, this could be the total permeability of an osmotic membrane times the difference in concentration across the membrane. So increasing the diffusion rate (e.g., increasing the permeability of the membrane material, decreasing its thickness or increasing its area) or increasing the concentration difference would speed up the diffusion rate. This general rule works for any type of diffusion including chemical and thermal.
Dynamic equilibrium can be more interesting than the description in the 1st answer implies. What's interesting is that the steady-state population must change to reflect changing birth rates (or death rates) because death rates are proportional to population. In the natural production and removal of carbon-14 (the basis of radiocarbon dating) in our environment, there is a constant rate of generation, and a rate of removal that depends on concentration. C-14 is generated at a constant rate as a constant flux of cosmic rays produces it by hitting a constant amount of atmospheric nitrogen. C-14 has a half-life of several thousand years; its rate of removal (conversion to C-12) depends on its concentration. An equilibrium concentration is achieved when it reaches the point where C-14 disappears at the rate it is generated.
