Question
Which of the below reactions corresponds with that which represents the standard enthalpy of combustion (also called “heat of combustion”) of butane, C4H10?
Which of the below reactions corresponds with that which represents the standard enthalpy of combustion of butane, C4H10?

Transcribed Image Text:**Quiz Question: Standard Enthalpy of Combustion**
Which of the below reactions corresponds with that which represents the standard enthalpy of combustion (also called “heat of combustion”) of butane, C₄H₁₀?
**Options:**
- A) \(4\text{CO}_2 (g) + 5\text{H}_2\text{O} (g) \rightarrow \text{C}_4\text{H}_{10} (g) + \frac{13}{2}\text{O}_2 (g)\)
- B) \(8\text{CO}_2 (g) + 10\text{H}_2\text{O} (g) \rightarrow 2\text{C}_4\text{H}_{10} (g) + 13\text{O}_2 (g)\)
- C) \(\text{C}_4\text{H}_{10} (g) + \frac{13}{2}\text{O}_2 (g) \rightarrow 4\text{CO}_2 (g) + 5\text{H}_2\text{O} (g)\)
- D) \(2\text{C}_4\text{H}_{10} (g) + 13\text{O}_2 (g) \rightarrow 8\text{CO}_2 (g) + 10\text{H}_2\text{O} (g)\)
**Explanation:**
This question asks which chemical equation represents the standard enthalpy of combustion of butane. The enthalpy of combustion refers to the heat change when one mole of a substance combusts completely in oxygen under standard conditions, producing carbon dioxide and water.
