Problem- Crystalline KCl has S*=83J/mol K and crystalline CaO has S*= 55 J.mol k. What accounts for the larger disorder in the KCl crystals?
a) Repulsive forces are larger for CaO
b) Attractive forces are larger for CaO
c) All oxides have lower entropy than all chlorides
d) Smaller size of CaO may accounts for lower entropy
e) It cannot be explained from the information given.
I need help for above question. Show each steps for the above problem
