How can the lowest G of a binary eutectic system be found?
Drawing a common tangent between the two minimas which indicates that the system can reduce G through existing as a mixture of two distinct solid phases.

What happens below T_E?
Common tangent drawn between the two minimas.

What happens when T>T_M (of both components) ?
G curves for liquid phase (so more stable) is lower than for solid phase.

Describe the Gibbs phase rule
It represents the criterion for the No. of phases that coexist within a system at equilibrium.
