Physical chemistry is the study of macroscopic, atomic, subatomic, and particulate phenomena in chemical systems in terms of laws and concepts of physics. It applies the principles, practices and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, dynamics and equilibrium.
Physical chemistry, in contrast to chemical physics, is predominantly (but not always) a macroscopic or supra-molecular science, as the majority of the principles on which physical chemistry was founded are concepts related to the bulk rather than on molecular/atomic structure alone (for example, chemical equilibrium and colloids).

Thermodynamics – does a reaction take place?
Each reaction has its own equation that gives its rate as a function of reactant concentrations. To determine the rate law we measure the rate at different starting concentrations.
