What is an example of a spontaneous exergonic reaction?

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
