Given the following information, calculate Δ(in kcal mol-1) for:  NaI(s) → Na+(g) + I-(g)

Process  Δ (kcal mol-1)
Na(s) → Na(g)  +26
I2(g) → 2 I(g)  +36 (per mole I2)
I2(s) → I2(g)  +15
Na(g) → Na+(g) + e-  +118
I(g) + e-→ I-(g)  -71
2 Na(s) + I2(s) → 2 NaI(s)  -699 (per mole NaI)  


▸ 816 kcal mol-1

▸ 823 kcal mol-1

▸ 562 kcal mol-1

▸ 746 kcal mol-1

▸ 798 kcal mol-1
