Hess's Law of Constant Heat Summation

Click on the button within the activity and use the example shown to calculate the reaction enthalpy, \(\Delta H\), for the following reaction:

\[ \text{CH}_4(g) + 2\text{O}_2(g) \rightarrow \text{CO}_2(g) + 2\text{H}_2\text{O}(l) \]

Use the series of reactions that follow:

1. \( \text{C}(s) + 2\text{H}_2(g) \rightarrow \text{CH}_4(g), \quad \Delta H = -74.8 \, \text{kJ} \)

2. \( \text{C}(s) + \text{O}_2(g) \rightarrow \text{CO}_2(g), \quad \Delta H = -393.5 \, \text{kJ} \)

3. \( 2\text{H}_2(g) + \text{O}_2(g) \rightarrow 2\text{H}_2\text{O}(g), \quad \Delta H = -484.0 \, \text{kJ} \)

4. \( \text{H}_2\text{O}(l) \rightarrow \text{H}_2\text{O}(g), \quad \Delta H = 44.0 \, \text{kJ} \)

Express your answer with appropriate units.
