For $2\,\text{NO}(g) + \text{O}_2(g) \rightarrow 2\,\text{NO}_2(g)$: $\Delta_f H^\circ$ of $\text{NO}(g)$ is $+90.25$ and of $\text{NO}_2(g)$ $+33.18\ \text{kJ mol}^{-1}$; the standard molar entropies are $\text{NO}(g)$ $210.8$, $\text{O}_2(g)$ $205.1$ and $\text{NO}_2(g)$ $240.1\ \text{J K}^{-1}\ \text{mol}^{-1}$. Take $\Delta H^\circ$ and $\Delta S^\circ$ as constant. Which of the following statements are correct?
