Hydrogen peroxide, $\text{H-O-O-H}$, breaks down to make water and oxygen. $2\text{H}_2\text{O}_2(g) \rightarrow 2\text{H}_2\text{O}(g) + \text{O}_2(g)$ The bond energies are given in the table. The reaction is exothermic. What is the energy change for the reaction?
- A$-346\,\text{kJ mol}^{-1}$
- B$-196\,\text{kJ mol}^{-1}$
- C$+196\,\text{kJ mol}^{-1}$
- D$+346\,\text{kJ mol}^{-1}$
