Calculate the overall energy change in kilojoules per mole for the formation of CaCL(s) from the elements. The following data are needed: (a) Eea for CL(g) = -348.6kj/mol. (b) Ei1 for Ca(g) = +589.8kj/mol. (c) Ei2 for Ca(g) = +1145kj/mol. Heat of sublimation for Ca(s) = +178.2kj/mol. Bond dissociation energy for Cl2(g) = +243kj/mol. Lattice energy for CaCL2(s) = +2258kj/mol. Lattice energy for CaCL(s) = +717kj/mol (estimated)
