Use the Following Data to Calculate the Lattice Energy of Lithium

question 82

Short Answer

Use the following data to calculate the lattice energy of lithium chloride, LiCl. $$\begin{array} { l r } { \text { Quantity } } & \text { Magnitude } ( \mathbf { k J } / \mathbf { m o l } ) \\\text { Ionization energy of } \mathrm{Li}(g) & 519 \\\text { Electron affinity of } \mathrm{Cl}(g) & -349 \\\text { Vaporization energy of } \mathrm{Li}(s) & 147 \\\text { Bond energy of } \mathrm{Cl}_{2}(g) & 240\\\text { Reaction enthalpy: } \mathrm{Li}(s)+\frac{1}{2} \mathrm{Cl}_{2}(g) \rightarrow \mathrm{LiCl}(s)&-409\end{array}$$
