Homework 8 [Due: Fri, Dec 7] - will not be accepted late. Solutions.
Note that for problem 8 it is not really necessary to distinguish the types of Gibbs free energy curves that occur when the A and B crystal structures are the same from when they are different. The curves shown for the case where they are different is the most general and most appropriate because typically we don't care what any of the curves are doing at high values of G.
