Question
Using the equations
2 C₆H₆ (l) + 15 O₂ (g) → 12 CO₂ (g) + 6 H₂O (g)∆H° = -6271 kJ/mol
2 H₂ (g) + O₂ (g) → 2 H₂O (g) ∆H° = -483.6 kJ/mol
C (s) + O₂ (g) → CO₂ (g) ∆H° = -393.5 kJ/mol
Determine the molar enthalpy (in kJ/mol) for the reaction
6 C (s) + 3 H₂ (g) → C₆H₆ (l).
![The image depicts chemical reactions along with their enthalpy changes (ΔH) written on graph paper. Here is the transcription and explanation:
1. Reaction 1:
- **Chemical Equation:**
\[
6\text{C(s)} + 3\text{H}_2\text{(g)} \rightarrow \text{C}_6\text{H}_6
\]
- **ΔH:** Moved and combined in the equations below.
2. Reaction 2:
- **Chemical Equation:**
\[
\frac{3}{2} (\text{C}_6\text{H}_6\text{(l)}) + \frac{15}{2}\text{O}_2\text{(g)} \rightarrow 15\text{O}_2\text{(g)} + 2\text{C}_6\text{H}_6\text{(l)}
\]
- **ΔH:** \(\text{ΔH: } 6271 = 3133.5\)
3. Reaction 3:
- **Chemical Equation:**
\[
(\cancel{\text{C}_6\text{H}_6\text{(l)}}) + \cancel{\frac{15}{2}\text{O}_2\text{(g)}} \rightarrow \cancel{\frac{21}{2}}\text{O}_2

4. Reaction 4:
- **Chemical Equation:**
\[
6\text{C(s)} + 3\text{O}_2\text{(g)} \rightarrow 6\text{CO}_2\text{(g)}
\]
- **ΔH:** \(\text{ΔH: } -393.5 \times 6 = -2361\)
5. Reaction 5:
- **Chemical Equation:**
\[
3\text{H}_2\text{O(l)} + 6\text{O}_2\text{(g)} \rightarrow \cancel{12\text{CO}_2\text{(g)}} - \text{C}_6\text{H}_6\text{(l)}
