9.37 d

For 37 part d) 4KClO3(s) => 3KClO4(s) + KCl(s) why are the products more ordered than the reactants, resulting in a negative entropy?

I believe it is because KCl is a very ordered crystal, giving it a lower entropy than KClO4 and KClO3 has less variability in where the Cl can be than KClO4, thus also resulting in lower entropy.
