Consider the reaction
2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(g)
for which ΔH° = 2.855x10^3 kJ and ΔS° = 92.70 J/K at 298.15 K.
(1) Calculate the entropy change of the UNIVERSE when 1.891 moles of C2H6(g) react under standard conditions at 298.15 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'.
