We saw in Section 6.7 that the reaction of solid sodium with gaseous chlorine to yield solid sodium chloride (NaCl) is favorable by 411 kJ/mol. Calculate the energy change for the alternative reaction that yields chlorine sodide (CI+Na™), and then explain why sodium chloride formation is preferred. 2 Na(s) + Cl₂(g) →2 CI+Na(s) Assume that the lattice energy for CI Na is the same as that for Na Cl. The following data are needed in addition to that found in Section 6.7: Eea for Na(g) = -52.9 kJ/mol Eil for Cl(g) = +1251 kJ/mol
