Le Châtelier’s Principle In chemistry, Le Châtelier’s Principle, can be used to predict the effect of a change in conditions on a chemical equilibrium It can be summarized as: If a chemical system at equilibrium experiences a change in concentration, temperature, volume, or partial pressure, then the equilibrium shifts to counteract the imposed change and a new equilibrium is established It is common to take Le Châtelier’s principle to be a more general observation, roughly stated: Any change in status quo prompts an opposing reaction in the responding system In chemistry, the principle is used to manipulate the outcomes of reversible reactions, often to increase the yield of reactions

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
