# Which has a greater entropy?

Which of the following has greater entropy?

a. $\ce{CH3COOH~ (aq)}$

or

b. $\ce{CH3COO^{-}~ (aq) + H+~(aq)}$

They are both in the same state, and have the same number of particles.. so how do I figure this out? My instinct says a, because the products will be more "random", but I'm not completely sure.. Any ideas?
