The reaction of hydrogen with oxygen gives out $486\ \text{kJ mol}^{-1}$ of energy. $2\text{H}_2(\text{g}) + \text{O}_2(\text{g}) \rightarrow 2\text{H}_2\text{O}(\text{g})$ The bond energy of H-H is $436\ \text{kJ mol}^{-1}$ and that of H-O is $464\ \text{kJ mol}^{-1}$. Calculate the bond energy of O=O?
- A$430\ \text{kJ mol}^{-1}$
- B$458\ \text{kJ mol}^{-1}$
- C$498\ \text{kJ mol}^{-1}$
- D$984\ \text{kJ mol}^{-1}$
