5. hařreloWith reference to the liquid-solid phase diagram below, label the four regions of the diagram appropriately. Consider that we have a mixture of composition xâ = 0.65 at T = 400°C. Describe (narrate) what is happening as we cool the melt down to the eutectic temperature (150°C). Describe the phases (liquid phase and solid B phase: remember the lever rule) and their respective relative molar amounts when this mixture is cooled to 200°C. (Refer to the Liquid-Solid [L-S] Phase Diagram; note that scoring for this item would be based on certain terms or phrases that are expected in describing a L-S profile).
