4H.7

Postby Amy Luu 2G » Sat Feb 08, 2020 11:55 am

For the reaction Cl2(g) + H2O(l) ---> HCl(aq) + HClO(aq) is there an increase or decrease in entropy?
I am confused as to why there is an increase in entropy. How do aqueous compare in entropy to solids, gases and liquids?

The answer key says for that equation there is a decrease in entropy, not an increase.

So the order of entropy in states are solids<liquids< aqueous solutions<gases.
Solutions have a greater entropy than pure liquids as the particles in a solution are more separated and solvent molecules separate the solute particles. There are more molecular positions this solution can take as opposed to a uniform liquid.
