Question
- A. endothermic reaction: correct Unit 4.5 answer for Energy transfer during exothermic and endothermic reactions
- B. Incorrect: confuses endothermic reaction with a nearby Energy changes idea
- C. Incorrect: gives a general chemistry statement without linking to Energy transfer during exothermic and endothermic reactions
- D. Incorrect: reverses the energy-change relationship in Exothermic and endothermic reactions
Answer
The correct option is endothermic reaction: correct Unit 4.5 answer for Energy transfer during exothermic and endothermic reactions.
Explanation
The correct option is endothermic reaction: correct Unit 4.5 answer for Energy transfer during exothermic and endothermic reactions. It directly supports the approved learning objective to explain that the temperature of the surroundings decreases during an endothermic reaction. This keeps the answer anchored to Energy transfer during exothermic and endothermic reactions within Exothermic and endothermic reactions, and avoids mixing energy transfer, reaction profiles, activation energy, chemical cells, fuel cells, exothermic reactions and endothermic reactions unless the objective names them.
Common mistake
Misunderstanding Temperature Change
Students often think that the temperature of the surroundings increases during an endothermic reaction.
Remember that in an endothermic reaction, energy is absorbed from the surroundings, causing the temperature of the surroundings to decrease.
