Thermodynamics (Classical) for Biological Systems
Self Evaluation Questions
The students can use the following questions to check their understanding of the material presented in the
course. If something is unclear, they can go back to the relevant lectures and clarify themselves. The
questions are arranged, module-wise, including the introductory module.
Module 6 Reaction Equilibria
1. What is the reaction coordinate (or extent of reaction)?
2. What are the conditions for equilibrium of a system in which bioreactions take place?
3. How does the phase rule get modified when bioreactions are taking place in the system?
4. How can KP, the equilibrium constant based on partial pressures, be expressed in terms of chemical
5. What are the relationships between (a) KP and KC (b) KP and Ky?
6. How are the equilibrium constants of gas phase reactions affected by temperature – give a quantitative
measure. Does pressure affect the same?
7. What are the differences between equilibrium constants for (a) gas phase reactions and (b) liquid or
solid phase reactions?
8. How do the equilibrium constants for liquid or solid phase reactions get affected by (a) temperature
and (b) pressure? (Quantitatively speaking)
9. Why do we need to study ionic equilibria?
10. What is the condition for equilibrium of a system in which ionic reactions take place?
