Ozone (O3\text{O}_3O3) in the upper stratosphere decomposes according to the following equation:
2O3(g)→3O2(g)ΔrH=−240 kJ mol−1 2\text{O}_3(\text{g}) \rightarrow 3\text{O}_2(\text{g}) \quad \Delta_{\text{r}} H = -240\text{ kJ mol}^{-1} 2O3(g)→3O2(g)ΔrH=−240 kJ mol−1At a high altitude, the molar gas volume is approximately 5.0 m3 mol-1.
What is the energy released, in kJ\text{kJ}kJ, during the decomposition of 2.0 m3 of ozone under these conditions?
