For the reaction \[ \begin{array}{l} 3 \mathrm{Fe}_{2} \mathrm{O}_{3}(\mathrm{~s})+\mathrm{H}_{2}(\mathrm{~g}) \longrightarrow 2 \mathrm{Fe}_{3} \mathrm{O}_{4}(\mathrm{~s})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \\ \Delta \mathrm{H}^{0}=-6.0 \mathrm{~kJ} \text { and } \Delta \mathrm{S}^{0}=88.7 \mathrm{~J} / \mathrm{K} \end{array} \] The maximum amount of work that could be done when \( \mathbf{2 . 4 4} \) moles of \( \mathrm{Fe}_{2} \mathrm{O}_{3}(\mathrm{~s}) \) react at \( \mathbf{3 1 2} \mathrm{K}, 1 \mathrm{~atm} \) is \( \square \) \( \mathrm{kJ} \). Assume that \( \Delta \mathrm{H}^{\circ} \) and \( \Delta \mathrm{S}^{\circ} \) are independent of temperature.

          For the reaction
\[
\begin{array}{l}
3 \mathrm{Fe}_{2} \mathrm{O}_{3}(\mathrm{~s})+\mathrm{H}_{2}(\mathrm{~g}) \longrightarrow 2 \mathrm{Fe}_{3} \mathrm{O}_{4}(\mathrm{~s})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \\
\Delta \mathrm{H}^{0}=-6.0 \mathrm{~kJ} \text { and } \Delta \mathrm{S}^{0}=88.7 \mathrm{~J} / \mathrm{K}
\end{array}
\]

The maximum amount of work that could be done when \( \mathbf{2 . 4 4} \) moles of \( \mathrm{Fe}_{2} \mathrm{O}_{3}(\mathrm{~s}) \) react at \( \mathbf{3 1 2} \mathrm{K}, 1 \mathrm{~atm} \) is \( \square \) \( \mathrm{kJ} \). Assume that \( \Delta \mathrm{H}^{\circ} \) and \( \Delta \mathrm{S}^{\circ} \) are independent of temperature.

For the reaction

3 Fe2O3( s)+H2( g) ⟶ 2 Fe3O4( s)+H2O(g)
ΔH^0=-6.0 kJ and ΔS^0=88.7 J / K

The maximum amount of work that could be done when 2 . 4 4 moles of Fe2O3( s) react at 3 1 2K, 1 atm is □ kJ. Assume that ΔH^∘ and ΔS^∘ are independent of temperature.
