Given the following information, calculate ΔH° (in kcal mol-1) for:  CaI2(s) → Ca+2(g) +2 I-(g)

Process  ΔH° (kcal mol-1)
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
I(g) + e-→ I-(g)   -71
Ca(s) + I2(s) → CaI2(s)  +534 (per mole CaI2)  

◦ 1359 kcal mol-1
◦ 1270 kcal mol-1
◦ 2356 kcal mol-1
◦ 1572 kcal mol-1
