Consider the reaction 2CO₂(g) + 5H₂(g) → C₂H₂(g) +4H₂O(g) for which AH° = 46.50 kJ and AS° = -124.8 J/K at 298.15 K. 1. Calculate the entropy change of the UNIVERSE when 1.643 moles of CO₂ (g) react under standard conditions at 298.15 K. ASuniverse J/K 2. Is this reaction reactant or product favored under standard conditions? reactant v 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'.
