Question

Sublimation energy of Ca is 121 kJ/mol. Dissociation energy of $\text{Cl}_2$ is 242.8 kJ/mol, the total ionization energy of $\text{Ca(g)} \to \text{Ca}^{2+}\text{(g)}$ is 2422 kJ/mol and electron affinity of Cl is –355 kJ/mol. Lattice energy of $\text{CaCl}_2$ is –2430.8 kJ/mol. What is $\Delta H$ for the process $\text{Ca(s)} + \text{Cl}_2\text{(g)} \to \text{CaCl}_2\text{(s)}$?
