THERMODYNAMICS: DETERMINATION OF THE ENTHALPY AND ENTROPY OF FUSION OF TRIPHENYLPHOSPHATE
OBJECTIVE
The objective of this experiment is to become familiar with experimental thermodynamics; this will be accomplished by using graphical methods to determine thermodynamic quantities (enthalpy and entropy of fusion) from experimentally acquired data.
QUESTIONS
1. Why was ΔSo obtained analytically rather than graphically?
2. Do you expect melting of TPP to be endothermic or exothermic? Why? Justify your answer using no more than 3 complete sentences.
3. Does your data and results confirm or deny your expectations from question 2? Why? Justify your answer using no more than 3 complete sentences.
4. What can you conclude about the relative "order" or "disorder" in the solid and liquid phases of TPP from the sign of ΔSo ? Explain using no more than 3 complete sentences.
5. Calculate the value of ΔGo for the melting of TPP 10o C above its normal melting point and 100 C below its normal melting point. Discuss the results of these calculations in terms of spontaneity of the melting process at these temperatures. You may assume ΔHo and ΔSo are independent of temperature.
