Answer to Question #84822 in Physical Chemistry for adarsh
Question #84822
Write down Born-Haber cycle for CaCl2 formation
Expert's answer
Born-Haber cycle for CaCl2
ΔHf = ΔHa(Ca) + 2*ΔHa(Cl) +ΔHI1 (Ca) + ΔHI2(Ca) + 2*ΔHea(Cl)+ ΔHLE
ΔHf = +178 kJ/mol + 2* (+121 kJ/mol) + 590 kJ/mol + 1145 kJ/mol + 2*(-346 kJ/mol) + (-2258 kJ/mol) = -795 kJ/mol
