Given the following data:
3CO2(g) + 4H2O(l) ⇌ C3H8(g) + 5O2(g)
∆H = 1, 110 kJ · mol−1
H2O(l) ⇌ H2(g) + 1/2O2(g)
∆H = 142.5 kJ · mol−1
3Cgraphite + 4H2(g) ⇌ C3H8(g)
∆H = −52 kJ · mol−1
calculate ∆H for the reaction
Cgraphite + O2(g) ⇌ CO2(g)
1. 1202 kJ · mol−1
2. −592 kJ · mol−1
3. 543 kJ · mol−1
4. −197 kJ · mol−1
5. −543 kJ · mol−1
