Reversible reaction activated only by thermal energy

  1. Jul 4, 2011 #1
    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,

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