Given the Following Information, Calculate ΔH°(in Kcal Mol-1) For: LiCl(s)

question 19

Multiple Choice

Given the following information, calculate ΔH°(in kcal mol-1) for: LiCl(s) → Cl-(g) + Li+(g) Process ΔH° (kcal mol-1)
Li(s) → Li(g) +37
Li(g) → Li⁺(g) + e- +124
Cl₂(g) → 2Cl(g) +29 (per mole Cl)
Cl(g) + e- → Cl-(g) -83
2Li(s) + Cl₂(g) → 2LiCl(s) -109 (per mole LiCl)

• A) +73 kcal mol-1
