Calculate the lattice energy of CaCl2 given the following thermodynamic data: Reactions                           &nbsp

Calculate the lattice energy of CaCl2 given the following thermodynamic data:

Reactions                                 Energies (kJ/mol)

Ca (s) --> Ca (g)    178.0

Ca (g) --> Ca+ (g) + e-                     590.0

Ca+ (g) --> Ca2+ (g) + e-                 1145

Cl2 (g) --> 2 Cl (g)                              242.6

Cl (g)   + e- --> Cl- (g)                        -348.7

Ca (s) + Cl2 --> CaCl (s)    ΔHof = -795.0
