Determination of Excess Molar Free Energy and Free Energy of Mixing

Question

Zinc and cadmium alloys conform to regular solution behavior. The following table shows the molar heats of mixing at various zinc concentrations at 723K.

  1. Calculate the excess molar free energy of mixing at Ncd = 0.85
  2. Calculate the molar free energy of mixing at Ncd = 0.85
  3. Does the solution exhibit a positive or negative deviation from ideal behavior?

Summary

This question belongs to chemistry and discusses about Zinc and cadmium alloys and to determine excess molar free energy of mixing and molar free energy of mixing at various zinc concentrations.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
