Problem Details

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
