Entropy

Q. Consider the reaction CO2(g) + H2(g) → CO(g) + H2O(l) for which ΔH° = 2.800 kJ and ΔS° = 76.80 J/K at 298.15 K. (1) Calculate the entropy change of the UNIVERSE when 2.160 moles of CO2(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'.
