Consider the reaction 3Fe2O3 (s) + H₂(g) → 2Fe3O4(s) + H₂O(g) for which AH° = -6.000 kJ and AS⁰ = 88.70 J/K at 298.15 K. 1. Calculate the entropy change of the UNIVERSE when 1.829 moles of Fe₂O3 (s) react under standard conditions at 298.15 K. ASuniverse = J/K 2. Is this reaction reactant or product favored under standard conditions? 3. If the reaction is product favored, is it enthalpy favored, entropy favored, or favored by both enthalpy and entropy? If the reaction is reactant favored, choose 'reactant favored'.

![**Chemical Reaction Analysis**
Consider the reaction:
\[ 3\text{Fe}_2\text{O}_3(s) + \text{H}_2(g) \rightarrow 2\text{Fe}_3\text{O}_4(s) + \text{H}_2\text{O}(g) \]
For this reaction, the standard enthalpy change (\(\Delta H^\circ\)) is \(-6.000 \, \text{kJ}\), and the standard entropy change (\(\Delta S^\circ\)) is \(88.70 \, \text{J/K}\) at \(298.15 \, \text{K}\).
1. **Calculate the entropy change of the universe** when \(1.829\) moles of \(\text{Fe}_2\text{O}_3(s)\) react under standard conditions at \(298.15 \, \text{K}\).
\[\Delta S_{\text{universe}} = \_\_\_\_\_\_ \, \text{J/K}\]
2. **Reaction Favorability**: Is this reaction reactant-favored or product-favored under standard conditions?
\[\_\_\_\_\_\_\_\_\_\_ \]
3. **If the reaction is product-favored**, determine whether it is enthalpy favored, entropy favored, or favored by both enthalpy and entropy. If the reaction is reactant-favored, choose 'reactant-favored'.
