Maybe I'm misinterpreting the text in the article due to the fact that english isn't my native language, but aren't most chemical reaction irreversible?
But to see if I get the principal of dynamic equilibrium:
Our body takes oxygen from our blood, but our lungs refill our blood with fresh oxygen. So this is an example of dynamic equilibrium within 'our' system?
- If you apply enough energy to the products of chemical reactions you can break them apart and form the reactants, so chemical reactions are reversible. The example above isn't really dynamic equilibrium because ther is no point of equilibrium. Our body uses the oxygen, the O2 that has been used doesn't return to the blood or the lungs. In dynamic equilibrium a reaction is producing the products and reactants at the same rate. Ex: water vapour is producing liquid water at the same rate that liquid water produces vapour. The concentrations of both the reactants and products stay the same at equilibrium. (Cabin Tom 13:57, 29 January 2006 (UTC))
[edit] Closed system
I don't think that closed system boundary conditions need apply for a dynamic equilibrium to exist. For example, in my line of work, ecological modelling, we often have systems in which state variables remain constant, while material (and energy for that matter) enters and leaves the model. All that matters (as I understand things) is that state variables are constant (or constrained within some periodic or quasi-periodic orbit) but remain there as a function of balancing processes.

[edit] Dynamic Thinking
I'm not sure how to see who wrote this but their interpretation of dynamic equalibrium using the bucket of water model helped a lot. This is something I've never really thought of and that example helped. Thanks.
[edit] Static Equilibrium
Should static equilibrium really redirect to Mechanical equilibrium ... is there any such thing as static equilibrium outside of mechanics?
