Le Chateliers principle

Can someone please explain le chatelier's principle?

[Patrick Ngo 2J]

From my understanding, Le Chatelier's principle shows that a system, or a chemical equation, will shift its equilibrium in order to counteract changes in different variables. For example, we know that the Kc of a reaction remains the same regardless of concentration -- Therefore, changing the system by doing something such as adding in reactants, will be counteracted by the system in order to maintain the same Kc. So, in the example of adding reactants, the equilibrium will shift so that products are favored. Hope this helps!

Hey there!

I am going to try and explain it in the simplest way possible. If we have are at equilibrium and that state is disturbed by changing conditions for instance the concentration, pressure, volume, or temperature, then our equilibrium will shift in the direction that counteracts the change that had occurred. There are some great videos online that help explain it and show examples if this explanation is hard to picture! I hope this helps!

Le Chatelier's principle describes how changing certain conditions of a reaction will affect the favored direction of a reaction. Since Kc is constant at a given temperature, for example, increasing the concentration of products or reactants at equilibrium will cause the reaction to shift towards producing more of the other. This is the sample principle that is applied for Kp. Finally, temperature also has an affect, as increasing the temperature will cause the reaction to shift more towards the endothermic reaction (since there is more energy that can be used to form the higher energy molecule), while decreasing the temperature will favor the exothermic reaction.

My understanding of Le Chatelier's principle states that when there is a change in a variable of a system that is at equilibrium, there will be a shift on the position of the equilibrium due to the change.

Le Chateliers principle describes how chemical reactions adjust in order to minimize the effect of changes. For example if reactants are added to a chemical reaction at equilibrium then the equation is no longer at equilibrium and the excess reactants will be converted to products until the ratio of R and P concentrations return to their value at equilibrium. This means that in other words the value of Q will increase increase until it is again equal to that of K. The same applies to a reaction where products are added except then the reverse reaction will occur until Q and P are again equal.

In simple terms the system will shift in the counteracting direction of the change in order to remain in equilibrium

[Gabrielle Linden 1C]

Le Chatelier's principle states that when a stress is applied to a system in dynamic equilibrium, the equilibrium tends to adjust to minimize the effect of the stress. This means that a reaction will respond to changing conditions, including a change in pressure, temperature, or concentration of products or reactants, by shifting its position of equilibrium to counteract the change. The position of equilibrium refers to the composition of the equilibrium mixture and whether it favors the products or reactants.

Hello! The way I see Le Chatelier’s Principle is that the chemical reaction will always want to be balanced and will try to stay in balance even when more products or reactants are added or subtracted.

If a chemical equation contains water in the liquid form and a question asks how the reaction will respond to an increase or decrease in water, is the answer no change because water as a liquid is not included in K expressions?

[James Bui 1D]

Le Chateliers principle is pretty much the affect of a reaction when something is alternated and not left constant during the reaction for example when you remove concentration of reactant or add temperature these things affect the reaction but not all affect equilibrium constant since all of them but temperature changes K.
