Consider the reaction
2Co(g) + 2NO(g)-
2CO2(g) + N2(g)
for which AH° = -746.6 kJ and AS° = -198.0 J/K at 298.15 K.
(1) Calculate the entropy change of the UNIVERSE when 2.358 moles of CO(g) react under standard conditions at 298.15 K.
ASuniverse =
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'.
