The reaction \( \text{N}_2\text{O}_5 \rightarrow \text{NO}_2 + \text{O}_2 \) is a chemical change rather than a physical change.
In a chemical change, the substances involved undergo a transformation that results in the formation of new substances with different chemical properties. In this case, \( \text{N}_2\text{O}_5 \) decomposes into nitrogen dioxide (\( \text{NO}_2 \)) and oxygen (\( \text{O}_2 \)), which are entirely different chemical species from the original compound.
In contrast, physical changes involve alterations in the state or appearance of a substance without changing its chemical identity, such as melting, boiling, or dissolving. Since the reaction results in the formation of new compounds, it qualifies as a chemical change.
