Le Chatelier’s principle | Chemical equilibrium | Chemistry | Khan Academy
In our text, we cover various topics, such as Reversible Chemical Reactions, Equilibrium, Equilibrium Constants (using and calculating), and Le Châtelier’s Principle.
Pick one of the above-mentioned topics and relate it to the below (claim it in your Subject heading), then provide the following information:

Research and briefly describe a real-life application of chemical equilibrium. How do we as a society benefit from equilibrium-driven processes? Sample contexts may include nutritional, medicinal, agricultural, industrial, commercial, or any other relevant application of your choice. Be sure to cite your sources.
Make sure to include any related formulas that you find. (You will want to use the D2L Chemistry equation editor when necessary)
