Reversible reaction activated only by thermal energy

Click For Summary
SUMMARY

The discussion centers on reversible reactions activated solely by thermal energy, with a specific example being the precipitation of sodium acetate from supercooled solutions. This process, often referred to as "Hot Ice," allows for the storage and release of thermal energy. The synthesis is straightforward and can be easily implemented in laboratory settings, making it an accessible demonstration of thermal energy storage. Participants emphasized the simplicity and effectiveness of this method compared to more complex biochemical processes like glycolysis.

PREREQUISITES
  • Basic understanding of reversible chemical reactions
  • Familiarity with thermal energy concepts
  • Knowledge of phase change materials
  • Experience with laboratory procedures for chemical synthesis
NEXT STEPS
  • Research the properties and applications of sodium acetate as a phase change material
  • Explore the process of creating supercooled solutions in a laboratory setting
  • Learn about the thermodynamics of reversible reactions
  • Investigate other examples of thermal energy storage systems
USEFUL FOR

Chemistry students, laboratory technicians, and researchers interested in thermal energy storage and reversible chemical processes.

Dear all,

I am not an expert of Chemistry and I would like to know if there is a reversible reaction that can be activated only by thermal energy. The result of the reaction should be something which can be brough again to the initial state, releasing again the thermal energy stored. I was thinking to something similar in concept to the glycolyse (in which the solar energy is stored in the molecule of glucose and this energy is released when the molecule is broken), but simpler to implement in lab. As I have understood, the synthesis of glucose is not simple and it does not require only thermal energy.

Please let me know.

Thanks a lot,
Stefano

The precipitation of sodium acetate from supercooled (achieved by heating) solutions does just that. Google "phase change materials thermal storage".
