Calculate the Energy Change for the Formation of LiCl(s)from Its

Multiple Choice

Calculate the energy change for the formation of LiCl(s) from its elements in their standard states and the following tabulated information: Li(s) + 1/2 Cl₂(g) → LiCl(s) ?
Li⁺(g) + Cl^-(g) → LiCl(s) -853 kJ/mol
Li(s) → Li(g) +159.4 kJ/mol
1/2 Cl₂(g) → Cl(g) +121.7 kJ/mol
Cl(g) + e^- → Cl^-(g) -348.6 kJ/mol
Li(g) → Li⁺(g) + e^- +520.2 kJ/mol

A) +1305.7 kJ/mol
B) +296.9 kJ/mol
C) -400.3 kJ/mol
D) -627.2 kJ/mol
