FIGURE 10.1 Observed K values for a series of aliphatic hydrocarbons at 150°R The data are from a variety of sources and represent a variety of compositions. The solid lines are empirical curve fits for the individual species. The dotted lines are calculated by Raoult s law. (Reprinted with permission from Yarborough, L.
