Web21 de ago. de 2024 · 1) atomization of the dihalide is the energy required to break the molecule into atoms ½X2 ( g) → X ( g) note that only F 2 and Cl 2 are gases in their natural state so the energies associated with atomization of Br 2 and I 2 requires converting the liquid or solid to gas first. Web11 de jul. de 2014 · In any case, the height of this line compared to the blue line (times Avogadro's number) is the enthalpy of vaporization. As you can see, it's a lot higher up. The reason is that for melting, the molecules just need enough energy to "slide" around each other, while for vaporization, they need enough energy to completely escape the well.
