The key is to understand that smaller quantum dots have a greater proportion of organic ligands, and disrupting the tightly packed ligand shell during dissolution is an endothermic process. Therefore, the correct explanation for the observed behavior is that the dissolution of smaller quantum dots is more endothermic due to the increased disruption of inter-ligand interactions."}
