SOLVED: Post-Laboratory Questions1. Is the process of dissolving potassium nitrate in water spontaneous at all temperatures used in this experiment? What value do you look at to determine this?2. Is the process of dissolving potassium nitrate endothermic or exothermic? How do you determine?3. Does the value for ΔS make sense in terms of order and disorder?4. Use the standard molar entropies below to calculate the standard molar entropy change for dissolving KNO3 in water. S values: KNO3 13
