Question

The break and halt temperatures found in the cooling curves of two metals A and B are given 16. below, Construct a phase diagram consistent with the given data. Label all regions of the diagram and give probable formulas of any compound that form 35 CHE2612/101/3/2019 Break/"C Halt 1/"C Halt 2/C Mol % B 0 1100 10,0 1060 700 20.0 1000 700 30.0 940 700 400 40,0 850 700 400 50,0 750 700 400 60.0 670 400 550 70.0 400 80,0 400 90.0 450 400 100.0 500 (10)

Answer 1

16

ANSWER

ACCORDING TO GIVEN DATA WE CAN CONSTRUCT A PHASE DIAGRAM THAT IS SHOWN IN THE BELOW FRO THE DIAGRAM WE CAN OBSERVE THAT EVERY HALT CORRESPONDING TO A LINE WHERE THREE PHASES ARE COEXIST IN EQUILIBRIUM AND EACH BREAK CORRESPONDS TO A BOUNDARY RANGE BETWEEN 1ST PHASE AND 2ND PHASE REGION THAT IS SHOWN BELOW HERE UNSTABLE COMPOUND IS LESS THEN 80%A AND MORE THEN 70% WE CHOOSE THE VALUE IN BETWEEN THESE TWO THAT IS 70% THE REMAINING VALUE SHOULD BE IN 25% THAT IS B VALUE TOTAL VALUE IS 100%
