WebReactivity then refers to the rate at which a chemical substance tends to undergo a chemical reaction in time. In pure compounds, reactivity is regulated by the physical properties of the sample. For instance, grinding a sample to a higher specific surface area increases its reactivity. WebThus, it can be understood that the primary difference between physical and chemical changes is that physical changes are reversible, whereas chemical changes are usually not.
