Significance of principle

Postby Clarice Chui 2C » Sat Jan 11, 2020 4:16 pm

What is the significance of Le Chatelier's Principle? How does it also apply to changing physical parameters?

Le Chatelier's principle is useful in describing how a chemical reaction shifts in response to changes in conditions. Changes in concentration of reactants or products, pressure, and temperature would result in shifts in the equilibrium, which is consistent with Le Chatelier's principle.

Le Chatelier's principle predicts how a change in the physical parameters and other factors in a system affects a reaction and makes it no longer at equilibrium. It predicts whether the reactants or products will be favored in order for the reaction to go back to equilibrium.

Le Chatelier's principle can be used to predict the behavior of a system due to changes in pressure, temperature, or concentration. This principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change to reestablish an equilibrium.

Le Chatelier's Principle is helpful in understanding that changes in concentration or pressure within the system will not affect K, and that the reaction will act accordingly so in order to keep K intact.

One of the most well-known applications of Le Chatelier's Principle is the production of NH3 for fertilizer. Dr. Lavelle mentioned it in lecture and one of the TA's talked about it in discussion

N2(g) + 3H2(g) --> 2NH3(g)
Chemist Fritz Haber highly pressurized the NH3 gas (with a catalyst) so that it became a liquid. The reaction thus "read" this as a decrease in product and ran forward to produce more product, NH3(g). This application of Le Chatelier's Principle lead to the manufacturing of fertilizer from a reaction with a very small K value

The Le Chatelier's Principle is responsible for describing which way a chemical reaction shifts due to its conditions. Specifically the changes involving temperature, pressure and the concentration of both products and reactants. Primarilly, this principle shows a change.
