Use an enthalpy diagram to calculate the lattice energy of $\mathrm{CaCl}_{2}$ from the following information. Energy needed to vaporize one mole of $\mathrm{Ca}(s)$ is $192 \mathrm{~kJ} .$ For calcium, the first $\mathrm{IE}=589.5 \mathrm{~kJ} \mathrm{~mol}^{-1}$, the second $\mathrm{IE}=1146 \mathrm{~kJ} \mathrm{~mol}^{-1}$. The electron affinity of $\mathrm{Cl}$ is $348 \mathrm{~kJ} \mathrm{~mol}^{-1}$. The bond energy of $\mathrm{Cl}_{2}$ is $242.6 \mathrm{~kJ}$ per mole of $\mathrm{Cl}-\mathrm{Cl}$ bonds. The standard heat of formation of $\mathrm{CaCl}_{2}$ is $-795 \mathrm{~kJ} \mathrm{~mol}^{-1}$.

Assume that $100.0 \mathrm{~mL}$ of $0.200 \mathrm{M} \mathrm{CsOH}$ and $50.0 \mathrm{~mL}$ of $0.400$ M HCl are mixed in a calorimeter. The solutions start out at $22.50^{\circ} \mathrm{C}$, and the final temperature after reaction is $24.28^{\circ} \mathrm{C}$. The densities of the solutions are all $1.00 \mathrm{~g} / \mathrm{mL}$, and the specific heat of the mixture is $4.2 \mathrm{~J} /\left(\mathrm{g} \cdot{ }^{\circ} \mathrm{C}\right)$. What is the enthalpy change for the neutralization reaction of $1.00 \mathrm{~mol}$ of $\mathrm{CsOH}$ in $\mathrm{kJ}$ ?
