Ozone, O₃(g), is a form of elemental oxygen that plays an important role in the absorption of ultraviolet radiation in the stratosphere. It decomposes to O₂(g) at room temperature and pressure according to the following reaction: 2 O₃(g) → 3 O₂(g) ΔH= -284.6 kJ b. Which has the higher enthalpy under these conditions, 2 O₃(g) or 3 O₂(g)?

Hey everyone's here. We have potassium chloride dissolving in water to form K plus and cl minus ions in the temperature of the solution decreases and were asked to identify which has a higher entropy potassium chloride or the K plus in K cl ions. So when the temperature of the solution decreases, this means that he is absorbed. So this is gonna be an endo thermic process. So DELTA H. It's positive in DELTA H. Other reactivates got me less than DELTA H. Of the products. So this means the K plus and cl minus ions have a higher entropy. Thanks for watching my video and I hope it was helpful.
