decomposition of Ca(NO,);:
> 2CaO(s) + 4NO,
• 1. Use the table of AH°; values to calculate AH°n of the
AH°
2Ca(NO,)2(0) → 2CaOs) + 4NO2() + O2(9)
Ca(NO,)2(6)
Cao (s)
NO2 (9)
2(g)
-938.2 kJ/mol
-634.9 kJ/mol
+33.2 kJ/mol
0 kJ/mol
O2 (9)
2. Using the following information, determine the AH°n for:
25(9) + 20F219) → SO2g) + SFA(9)
rxn
4(g)
AH° = -277 kJ
+ 2HF(g)
+ 4HF(g)
OF2(9) + H2O0 → O2(g)
+ 2H,O,> SO,19) + 4HF
SFACO)
AH° = -828 kJ
AH° = -279 kJ
S(9) + O21g) > SO2(9)
→ SO2
+ O2(9)
