Aluminum forms a layer of aluminum oxide when exposed to air which protects the bulk metal from further corrosion.
         4Al(s) + 3O2(g) → 2Al2O3(s)
Using the thermodynamic data provided below, calculate ΔS° for this reaction.
         
 
S°(J/K·mol)
Al(s)  
     28.3
O2(g)  
   205.0
Al2O3(s)
     50.99
 

◦ 182.3 J/K·mol
◦ 131.5 J/K·mol
◦ –182.3 J/K·mol
◦ –626.2 J/K·mol
◦ –802.9 J/K·mol
