Q11MAtomic StructureFree sample

Equations involving four enthalpy changes are shown.

Na(g)→Na+(g)+e−ΔH=WNa(g)→Na2+(g)+2e−ΔH=XNa(s)→Na(g)ΔH=YNa(s)→Na2+(g)+2e−ΔH=Z\begin{aligned} \text{Na(g)} &\rightarrow \text{Na}^+(\text{g}) + \text{e}^- &\Delta H &= W \\ \text{Na(g)} &\rightarrow \text{Na}^{2+}(\text{g}) + 2\text{e}^- &\Delta H &= X \\ \text{Na(s)} &\rightarrow \text{Na(g)} &\Delta H &= Y \\ \text{Na(s)} &\rightarrow \text{Na}^{2+}(\text{g}) + 2\text{e}^- &\Delta H &= Z \end{aligned}
