Refer to Figure 22-3 and then construct an enthalpy diagram for forming XeO₃(g) from Xe(g) and O₂(g). For XeO₃, the average bond enthalpy is about 36 kJ mol^–1, and for O₂, the bond enthalpy is 498 kJ mol^–1 What is Δ_fH° for XeO₃(g)? Does your result support the observation that Xe(g) does not react directly with O₂(g) to form XeO₃(g)?
