BARC-16: Using Gibb’s Phase rule for a Binary Eutectic alloy, the maximum number of Phases that can co-exist at equilibrium are 4 (F=0, P = C+2 = 4). Then at the Eutetic point there should be 4 phases but we find only 3? Explain

As a part of BARC interview Prepartion, We will post one Conceptual Question Daily. BARC-1: In a Eutectic Phase Diagram, Lever Rule can be applied just above Eutectic Temp or Just below. But not at the Eutectic Temp. What is the Reason?
