Question
- A. reaction profile: correct Unit 4.5 answer for Reaction profiles
- B. Incorrect example: uses a device, reaction, or diagram not linked to reaction profile
- C. Incorrect example: gives evidence without explaining the energy transfer
- D. Incorrect example: describes a broad practical skill instead of the objective
Answer
The correct option is reaction profile: correct Unit 4.5 answer for Reaction profiles.
Explanation
The correct option is reaction profile: correct Unit 4.5 answer for Reaction profiles. It directly supports the approved learning objective to draw a simple reaction profile for an endothermic reaction. This diagram version keeps the answer anchored to Reaction profiles 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
Mislabeling Reaction Profiles
Students often label the energy change in an endothermic reaction profile incorrectly, indicating it as a decrease instead of an increase.
Remember that in an endothermic reaction, the products have more energy than the reactants, so the energy change should be labeled as an increase.
