I’m curious about the principles behind heat release and absorption in chemical reactions. What determines whether a reaction releases heat (exothermic) or absorbs heat (endothermic)? Is it related to specific types of bonds breaking or forming, or are there other factors involved?
In: Chemistry
Yes they bonds store energy. Just like a compressed spring that makes something move quickly when released. Quickly moving molecules IS heat.
Now some reactions replace somewhat compressed springs with very compressed springs, that is only possible when energy is added from the outside, that’s endothermic.
Usually most systems want to be in balance, so they strife for the most relaxed way to arrange their springs.
