Calculate the entropy change of the UNIVERSE when 2.001 moles of H2O(g) react under standard conditions at 298.15 K.

Consider the reaction

2H2O(g) + 2Cl2(g)4HCl(g) + O2(g)

for which H° = 114.4 kJ and S° = 128.9 J/K 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'.
