The difference between a physical reaction and a chemical reaction is composition.

Chemical Change vs. Physical Change

In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.

Thus, we shall simply refer to physical "reactions" as physical changes from now on.
