Discussion questions 1. Did molar solubility increase or decrease with increasing temperature? 2. Based on the experimentally determined AH value, is the dissolution of KNO3 endothermic or exothermic? 3. Based on the experimentally determined AS value, is the dissolution of KNO3 correspond to an increase or decrease in entropy? 4. Provide a molecular level explanation to account for the signs of AS rxn and AHrxn
