Question

The free energies of formation, GM, of liquid Sn-Cu alloys at 1400 K, as a function of composition, are listed below. From this data calculate the composition dependencies of aSn and aCu at 1400K​

Answer 1

Explanation:

The free energy of formation, AG of of liquid Sn-Cu alloys at 1400 K, as a function composition, are listed below. From these data, plot the composition dependencies of the activity of Sn (asn) and Cu (acu).
