Ozone decomposes in the upper atmosphere according to the following equation:

2\text{O}_3(\text{g}) \rightarrow 3\text{O}_2(\text{g}) \quad \Delta_{\text{r}} H = -288\text{ kJ mol}^{-1}

At a certain altitude, the molar gas volume is approximately 8.0 m³ mol^-1.

What is the energy released, in $kJ\text{kJ}$ , during the decomposition of 12.0 m³ of ozone under these conditions?

$144$

$216$

$432$
