Question
Describe one way an exam question could test thermal decomposition in Energy transfer during exothermic and endothermic reactions.
Answer
It could test a definition, comparison, calculation, observation, structure-property relationship, or explanation depending on the objective wording.
Explanation
This answer is correct because it directly supports the approved learning objective: Identify thermal decomposition and the reaction of citric acid with sodium hydrogencarbonate as examples of endothermic reactions. It stays inside Energy transfer during exothermic and endothermic reactions, uses thermal decomposition as the revision focus, and gives the Chemistry reasoning needed for an exam-style response.
Common mistake
Confusing Endothermic Reactions
Students often confuse thermal decomposition with exothermic reactions, thinking they release energy instead of absorbing it.
Remember that thermal decomposition is an endothermic reaction that takes in energy from the surroundings, while exothermic reactions release energy.
