Which type of chemical reaction absorbs heat energy from its surroundings?

• A. Neutralization reaction
• B. Combustion reaction
• C. Exothermic reaction
• D. Endothermic reaction

Answer: (D)

Verified step by step guidance

1. Understand the difference between exothermic and endothermic reactions: Exothermic reactions release heat to the surroundings, while endothermic reactions absorb heat from the surroundings.
2. Identify the key characteristic of the reaction in question: Since the problem asks for the type of reaction that absorbs heat, focus on reactions that require energy input.
3. Review the given options: Neutralization reactions typically release heat (exothermic), combustion reactions release heat (exothermic), and exothermic reactions by definition release heat.
4. Recognize that the correct type of reaction absorbing heat is an endothermic reaction, which is not listed among the options but is the correct classification.
5. Conclude that the reaction absorbing heat energy from its surroundings is an endothermic reaction, characterized by a positive enthalpy change (\(\Delta H > 0\)).
