|To the naked eye, equilibrium seems dead. But at the molecular level,
its forward and reverse reactions are very much alive; it's just that their work, cancels each other out,
producing no observable change. |
Look at this flower (an aster),
and you see no immediate colour change.
In reality, however, different anthocyanin pigments are at equilibrium with each other.
Change the pH, which throws off the balance by favouring only one of the reactions, and the colour will change.
The doors of perception will have been cleansed. (But I don't think that's what William Blake had in mind
when he wrote it.)
