WebPositive and negative departures from Raoult's Law for a binary solution are schematically illustrated in Fig. 3.3.1. Attention is directed to the following facts: (a) If one component exhibits a positive (negative) departure from Raoult's Law, the other must do likewise; a proof for this statement is to be furnished in Exercise 3.3.2.
