The balanced equation for the complete combustion of ethyne, $\text{H-C} \equiv \text{C-H}$, is given below. $2\text{H-C} \equiv \text{C-H} + 5\text{O}=\text{O} \rightarrow 4\text{O}=\text{C}=\text{O} + 2\text{H-O-H}$ A list of bond energies is provided. What is the enthalpy change for the reaction when $1\,\text{mol}$ of ethyne is completely burned?
- A$-2472\,\text{kJ mol}^{-1}$
- B$-1236\,\text{kJ mol}^{-1}$
- C$+1236\,\text{kJ mol}^{-1}$
- D$+2472\,\text{kJ mol}^{-1}$
