c6h12o6(s)<--->c6h12o6(aq)+q
if we increase temp why does solubility decrease.according to le chatlier's principle it should decrease.can anyone explain it to me.

does it involve kinetic molecular theory or something i just saw it in a book.

does solubility increse for solids only only or does it increase for liquids too?

Le chatiliers principle states that if a reaction is in equilibrium and that equilibrium is disturbed the reaction will shift to yield relieve the stress placed on it by the disturbance.
In your balanced equation there on the right most side of the equation there is Q which means heat. This means for the reaction to proceed to finish heat is produced. As you increase the temperature this increase in heat will lower the reaction. It is harder to produce heat when it is very hot, it requires more energy and thus will decrease the solubility.

This website seems to explain it pretty well.

An increase in the temp. of a solution *increases* the solubility of a *solid or liquid* solute.
An increase in the temp. of a solution *decreases* the solubility of a *gas* solute.

oh if the substance is a gas, solubility decreases when temperature increases. if it's a liquid, then chatlier's principle is true; as temp increases then solubility decreases....

Gosh, when you get the answer to that, email me please I sure would like to know what the heck all that means!
