![### Enthalpy Calculation Using Given Reactions
#### Using the equations:
1. \( \text{H}_2 (g) + \text{F}_2 (g) \rightarrow 2 \text{HF} (g) \quad \Delta H^\circ = -79.2 \, \text{kJ/mol} \)
2. \( \text{C} (s) + 2 \text{F}_2 (g) \rightarrow \text{CF}_4 (g) \quad \Delta H^\circ = 141.3 \, \text{kJ/mol} \)
3. \( 2 \text{C} (s) + 2 \text{H}_2 (g) \rightarrow \text{C}_2\text{H}_4 (g) \quad \Delta H^\circ = -97.6 \, \text{kJ/mol} \)
#### Determine the enthalpy for the reaction:
\[ \text{C}_2\text{H}_4 (g) + 6 \text{F}_2 (g) \rightarrow 2 \text{CF}_4 (g) + 4 \text{HF} (g) \]
### Tools Available:
On the right side, there is a calculator interface with:
- A keypad with numbers \(1-9\), \(0\), a negative sign \(-\), and a decimal point \(. \)
- Two function buttons: a delete button and a clear (C) button.
- A button to multiply by \(10^x\).
Use these to perform calculations based on the thermochemical equations given.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F56c0d6f8-9f13-42b8-9b57-0cbb0f2f598f%2Fa2209b98-ef78-4c38-8920-c47bb622d5e3%2Fyjsut58_processed.png&w=3840&q=75)
