To accurately characterize the compounds that exhibit reduced solubility as temperature rises based on the graph you mentioned, we need to identify which specific compounds exhibit this behavior.
Generally, many ionic compounds (like NaCl) become more soluble with increasing temperature, while some gases (like NH3) and certain other compounds may have decreased solubility as temperature increases.
Since I cannot see the graph you reference, I would need you to verify which compounds show reduced solubility as the temperature increases. However, based on typical behavior, if you have seen from the graph that only NH3 shows reduced solubility with rising temperature, the correct response would be:
NH3 only
If both NH3 and another compound (e.g., Ce2(SO4)3) exhibit reduced solubility with increasing temperature, the response might be:
NH3 and Ce2(SO4)3 only
If NaCl shows typical behavior (increased solubility with temperature), then it would not be included in the correct response regarding reduced solubility.
Please check the graph for precise data to determine which compounds exhibit reduced solubility with rising temperature.
