The quantity of 83.0 g of potassium iodide (KI) is added to water to give a solution with a mass of 150. g. Assume that this solution is very dilute and thus has the same heat capacity as water. The dissolution reaction and the associated heat for potassium iodide is KI (s) -→ K+(aq) + I-(aq) qrx = DHrx = +20.3 kJ. Calculate the change in the temperature of the solution.
In a typical cold pack (used for sports injuries), a salt such as ammonium nitrate is kept in a separate pouch from a bag of water. When the pouch is punctured, the salt readily dissolves in the water, and the pack becomes noticeably cooler to the touch (temperature decreases from room temp to about 5 oC). Based around le Charlier principle conclude the signs for ΔHº, ΔSº, and ΔGº for the solvation of ammonium nitrate in water.

A 5.00 g-sample of KOH at 25.0 C was added to 100.0 g of H2O(l) at room temperature inside an insulated cup calorimeter, and the contents were stirred. After all the KOH(s) dissolved, the temperature of the solution had increased. Based on the information given, which of the following best justifies the claim that the dissolution of KOH is a thermodynamically favorable process? A. The forces between the ions and the water molecules are stronger than the forces between water molecules, thus, delta H < 0. Also, the ions become less dispersed as KOH(s) dissolves, thus delta S > 0. Therefore, delta G < 0. B. The energy require to break the bonds between the ions in the solid is less than that released as the ion-dipole attractions form during solvation, thus delta H < 0. Also, the ions become widely dispersed as KOH(s) dissolved, thus delta S > 0. Therefore, delta G < 0. C. The average kinetic energy of the particles increases, resulting in delta H > 0. Also, the…
