Writing Conceptual Questions (CQs): Modified Recall with Reason
Modify a recall question or an algorithmic calculation so it requires a student to give a qualitative answer; for example, a list of increasing or decreasing properties or "higher", "lower", or "no change". Then ask for a reason.
Original recall question: Which set of conditions would give a reaction that is spontaneous under all conditions?
Ho < 0, So < 0
Ho = 0, So = 0
Ho < 0, So > 0
Ho > 0, So > 0
Ho > 0, So < 0
A conceptual question with a reason: Each of the reactions below is spontaneous at 25oC when P = 1 atm. Which is (are) required to be exothermic?
