Effect of Temperature on Solubility

  1. Nov 11, 2016 #1
    Solubility of some some solids decrease with increase in temperature...There is an exothermic reaction so a lot of heat is produced in the solution...My question is that why does solubility decrease???...Any increase in temperature (the heat we provide) should just excite the molecules more and the solubility should increase....

    Nope. You are ignoring half of the thermodynamics here, and it is not just a matter of solubility, but of all exothermic reactions.

    What does the LeChatelier's principle predict?

    What about ΔG? It has two parts, one is about heat, the other is about entropy change.
