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 1.704 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'.
