Consider the reaction 2C₂H6 (9) +702 (9)→ 4CO2 (g) + 6H₂O(g) for which AH° = -2855 kJ and AS = 92.70 J/K at 298.15 K. 1. Calculate the entropy change of the UNIVERSE when 1.818 moles of C₂H6 (9) react under standard conditions at 298.15 K. A Suniverse = 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'.
