Chapter 6, Problem 6.86SP

Calculate the overall energy change in kilojoules per mole for the formation of CsF(s) from its elements using the following data:
$\begin{array}{l}{E}_{\text{ea}}\text{for F}\left(g\right)=-\text{328 kJ/mol}\\ E_{\text{i1}}\text{for Cs}\left(g\right)=+\text{375}.\text{7 kJ/mol}\\ E_{\text{i2}}\text{for Cs}\left(g\right)=+\text{2422 kJ/mol}\\ \text{Heat of sublimation for Cs}\left(s\right)=+\text{76}.\text{1 kJ/mol}\\ {\text{Bond dissociation energy for F}}_{\text{2}}\left(g\right)=+\text{158 kJ/mol}\\ \text{Lattice energy for CsF}\left(s\right)=+\text{74}0\text{ kJ/mol}\end{array}$
