Chemical Engineering Thermodynamics

Third law of thermodynamics is helpful in

  • A. Prediction of the extent of a chemical reaction
  • B. Calculating absolute entropies of substances at different temperature
  • C. Evaluating entropy changes of chemical reaction
  • D. Both B and C
Answer: Option D.

Since the third law of thermodynamics is concern about entropy of a pure crystalline substance at absolute zero temperature this can be used as a reference.
