Question

Define Le Chatelier’s Principle in your own words. Then, describe an everyday example (not strictly related to our course) of Le Chatelier’s Principle in nature.

Answer 1

Le Chatelier’s Principle can be defined as :
If a system at equilibrium is subjected to any change, then the system has a tendency to shift the reaction in the direction that reduces the effect of this change.
For example, if we incraese the temperature , the system will try to shift in that direction which will reduce the temperature. This is true for any changes.

A physical example will be decomposition of calcium carbonate for the production of lime.
CaCO 3 (s) <----> CaO (s) + CO 2 (g).
If we add more of CaCO3 then system will shift towards right and more of Cao and CO2 will be formed. You can see the movement of reaction towards right as more gas will be released
