physical chemistry
Equations meet reactions
Physical chemistry is the branch of chemistry that applies the principles and methods of physics to understand chemical systems and processes.
It examines how matter behaves at the molecular and atomic level, focusing on topics like thermodynamics, quantum mechanics, kinetics, and spectroscopy.
Physical chemists study why reactions occur, how fast they proceed, and what energy changes accompany them.
Her research in physical chemistry helped explain how catalysts speed up industrial processes.
