体Evaluate bei,tegral LI~le-m (2+Hadydzuingcylindrical coordi (a2 + ) dz dy dx using cylindrical coordinates.

Estimate the lattice energy for LiCl given the following thermochemical data: Li(s) rightarrow Li(g) Delta H f^+ [Li(g)] = 159.3 kJ/mol 1/2 Cl_2(g) rightarrow Cl(g) Delta H f^+ [Cl(g)] = 121.7 kJ/mol Li(g) rightarrow Li^+ (g) + e^- IE_2(Li) = 520 kJ/mol Li(s) + 2 Cl_2(g) rightarrow LiCl(s) Delta H^f [LiCl(s)] = -408.3 kJ/mol Cl(g) + e^- rightarrow Cl^-(g) EA(Cl) = 349 kJ/mol a) -3406 kJ/mol b) -2720. kJ/mol c) 2720. kJ/mol d) 860 kJ/mol e) None of these choices is correct.
