Calculate Delta Sdeg at 25deg C for the reduction of PbO(s),2PbO(s)+C(s)->2Pb(s)+CO_(2)(g) given these absolute entropies:
Sdeg
(J/K.mol)
PbO(s),69.45
C(s) ,5.7
Pb(s),64.89
CO2(s) 213.6
+198.8 J/K·mol
+353.6(J)/(K)*mol
-203.3(J)/(K)*mol
+203.3 J/K·mol
+488.0(J)/(K)*mol
Calculate S at 25C for the reduction of PbO(s),2PbO(s) + C(s)- 2Pb(s) + CO(g) given these absolute entropies
so
(J/K.mol) PbO(s) 69.45 C(s) 5.7 Pb(s) 64.89 CO2(s) 213.6
+198.8 J/K.mol
+353.6J/K.mol
-203.3 J/K.mol
+203.3J/K.mol
+488.0J/K-mol
