Le Chatelier's Principle

[Emily Orozco L4]

This principle applies to changing what physical parameters?

[peteryim]

Le Chatelier's Principle applies fundamentally to changes in temperature, pressure, or concentration. Changing other physical parameters will matter when they affect these three factors. For example, changing the volume of the container in which the reaction takes place effects the concentration of the reactants/products, which is why Le Chatelier's Principle becomes relevant.

Le Chatelier's Principle applies to temperature, concentration, and pressure, but it doesn't apply to catalysts because catalysts speed up the forward and reverse reactions at the same rate.

[Joowon Seo 3A]

It applies if the physical parameters are produced. For example, if a reaction produces heat, more reactions will be favored to form reactants if we add heat.

[Emma Popescu 1L]

Le Chatelier's principle states that chemical reactions adjust so as to minimize the effect of changes, which applies to temperature, pressure and concentration.
