| Apr 14, 2016 at 16:40 | comment | added | matt_black | @HenryStone adding to Brian's comments: biological systems are often even more complex as enzymes often direct reactions down a small hard-to-find path between one valley and another (in some cases by altering the landscape, though we risk getting lost in analogy land if we go to far with this idea). | |

(2) Approximately speaking, yes, there is a kind of chemical momentum; see reaction dynamics. (3) Yes, there is an element of "chance" (technically, of statistics) to the progression of a reaction. | |
| Apr 14, 2016 at 13:57 | comment | added | Henry Stone | That makes a lot of sense! One thing, though: When it reaches the peak, what prevents the "ball" from rolling back the side it came from? Is there some kind of chemical momentum (bad analogy, my sincerest apologies, but...) or is it a matter of chance (which would create a lot of other interesting questions...)? | |
