Which term describes the ability of a substance to react?

• A. Chemical Property
• B. Physical Property
• C. Physical Changes
• D. Chemical Changes

Answer: (A)

The ability of a substance to react is described by a chemical property. This explains how a substance behaves in chemical reactions and whether it changes composition when it encounters other substances or conditions. Physical properties are attributes you can observe without changing what the substance is—things like color, density, or melting point. Physical changes alter form or state but not the substance’s identity. Chemical changes produce new substances, and reactivity is a hallmark of that type of change. So, the term that captures the ability to react is chemical property.
