What does physical chemistry tell us about chemical reactions?
We’ve also got chemical reactions (bet you didn’t see that one coming)! So physical chemistry tells us of the kinetics, like how things react so it has implications in organic, inorganic, and materials. Also, engineering - concrete is actually an incredibly difficult reaction to understand. So just to let that sink in for a sec… every chemical reaction belongs to physical chemistry (kinda but there was a huge amount of progress in physical organic chemistry and inorganic chemistry). And finally, if we want to cast our net out further (and I do), all of biology follows the laws of thermodynamics and culminates in biophysical chemistry.
