The partition coefficient K, the equilibrium constant for partitioning between oil and water, for butyric acid is about 10^–2, and for 1,4-butanediol it is about 10^–4.  You add liposomes containing only water to a solution with an initial concentration of 1 mM butyric acid and 100 mM 1,4-butanediol outside the liposomes.  What is the relative rate of diffusion of the two substances into the liposome interior?
