Higher Chemical Concentration = Higher Temperature of Precipitation. Why?

[ctaconquer]

If two chemicals are mixed together

If I had varying concentrations of the reactant solutions, why is it that the higher concentration mixtures will precipitate at a higher temperature? and lower concentration chemicals will precipitate at a lower temperature?

i honestly have no clue what this is all about but someone else posted up that same question and got some posts here: https://www.physicsforums.com/showthread.php?t=162382
hope that helps

This phenomenon can be explained by the principle of Le Chatelier's principle, which states that when a system at equilibrium is subjected to a stress, it will shift in a way that minimizes the effect of that stress. In this case, the stress is the addition of more reactant molecules in the higher concentration mixture.

When two chemicals are mixed together, a reaction occurs to form a precipitate. This reaction releases energy in the form of heat, which increases the temperature of the mixture. As more reactant molecules are added in the higher concentration mixture, the equilibrium of the reaction is shifted towards the products side, resulting in a higher yield of the precipitate. This increased production of the precipitate releases more heat, causing the temperature to rise even further.

On the other hand, in a lower concentration mixture, there are fewer reactant molecules available to form the precipitate. This leads to a lower yield of the precipitate, resulting in less heat being released and a lower temperature of precipitation.

In summary, the higher concentration of reactant molecules leads to a greater production of the precipitate, which in turn releases more heat and results in a higher temperature of precipitation. This is a direct result of the Le Chatelier's principle and the laws of thermodynamics.
