Calculation of Temperature of Allotropic Transformation and Melting Temperature

Question

a)The free-energy temperature diagram shown below, determine:

  1. The melting temperature
  2. The temperature of allotropic transformation.
  3. Explain the negative slopes and negative curvatures. why?

 b)Based on the part of a phase diagram below:

  1. List the phases in the order of increasing density.
  2. Sketch the Gibbs free energies of all phases as function of temperature at pressure (P1)
  3. Sketch the Gibbs free energies of all phases as function of pressure at temperature (T1)

Note: both slopes of curvatures of the lines should be apparent from your plots.

Summary

This question belongs to chemistry and discusses about the free-energy temperature diagram and to determine temperature of allotropic transformation and melting temperature.

    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
