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 (a) What is the enthalpy change for this reaction per mole of O3(g)? (b) Which has the higher enthalpy under these conditions, 2 O3(g) or 3 O2(g)?
