Question
Consider the reaction
2C2H6(g) + 7O2(g)4CO2(g) + 6H2O(g)
for which H° = -2.855×103 kJ and S° = 92.70 J/K at 298.15 K.
(1) Calculate the entropy change of the UNIVERSE when 2.398 moles of C2H6(g) react under standard conditions at 298.15 K.
Suniverse = J/K
(2) Is this reaction reactant or product favored under standard conditions?
_________reactantproduct
(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'.
