Sulfur can be separated from lead in the mineral galena, PbS(s), by “roasting” the ore in the presence of oxygen as shown in the following reaction:
         2PbS(s) + 3O2(g) → 2PbO(s) + 2SO2(g)
Calculate ΔS° for this reaction using the thermodynamic data provided below.
         
 
S°(J/K·mol)
PbS(s)  
     91.2
O2(g)  
   205.0
PbO(s)  
     69.45
SO2(g)  
   248.5
 

◦ –410 J/K·mol
◦ –161.5 J/K·mol
◦ –47.7 J/K·mol
◦ 21.8 J/K·mol
◦ 43.5 J/K·mol
