Question



Consider the reaction

2H2S(g) + 3O2(g)2H2O(l) + 2SO2(g)

for which H° = -1.124×103 kJ and S° = -390.7 J/K at 298.15 K.

(1) Calculate the entropy change of the UNIVERSE when 2.296 moles of H2S(g) react under standard conditions at 298.15 K.
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'.
