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

Process  Δ (kcal/mole)
Ca(s) → Ca(g)  +178
I2(g) → 2 I(g)    +36 (per mole I2)
I2(s) → I2(g)    +15
Ca(g) → Ca+(g) + e-  +590
Ca+(g) → Ca+2(g) + e-  +1145
CaI2(s) → Ca+2(g) +2 I- (g) +1288
Ca(s) + I2(s) → CaI2(s)  +534 (per mole CaI2)  


▸ -715 kcal mol-1

▸ -338 kcal mol-1

▸ -89 kcal mol-1

▸ -71 kcal mol-1

▸ -142 kcal mol-1
