What is the Le Chatelier principle quizlet? ›

Le Châtelier's principle predicts that when the pressure of an equilibrium system is increased, due to a decrease in volume, the system will shift in the direction that decreases the total moles of gas in the system to minimize the stress.

Le Chatelier's principle can be stated as follows: A change in one of the variables that describe a system at equilibrium produces a shift in the position of the equilibrium that counteracts the effect of this change.

Final answer: The correct description of Le Châtelier's principle is that a system at chemical equilibrium will adjust to changes by shifting in a direction to regain equilibrium.

Le Chatelier's principle implies that a pressure increase shifts an equilibrium to the side of the reaction with the fewer number of moles of gas, while a pressure decrease shifts an equilibrium to the side of the reaction with the greater number of moles of gas.

Le Chtelier's principle states that any change to a system at equilibrium will adjust to compensate for that change. If the pressure is increased, the position of equilibrium will move so that the pressure is reduced again.

Le Châtelier's principle states that a system at equilibrium will respond to a stress on the system in such a way so as to relieve the stress and establish a new equilibrium.

Le Chatelier's Principle Examples

Concentration: In a system where the reaction A + B ⇌ C + D is currently in equilibrium, increasing the concentration of one of the reactants, e.g., 2 A + B ⇌ C + D , will cause a shift in equilibrium to the right.

The Le Chatelier principle states that the sensitivity of input demands with respect to own price variations is smaller when the output level is held constant than when it is adjusted.

Le Chatelier's principle predicts that equilibrium will shift to decrease the concentration of reactants. Increasing the rate of the forward reaction will mean a decrease in reactants. So some of the sulfur dioxide or oxygen is used to produce sulfur trioxide.

The best description of Le Chatelier's Principle is option C) a reaction which is at equilibrium, when disturbed, will react appropriately to reestablish equilibrium.

What happens when the Le Chatelier's principle occurs? ›

According to Le Chatelier's principle, when the concentration of a product is reduced in a chemical reaction that was in equilibrium The equilibrium shifts to the right to favor the formation of products.

What does Le Chatelier's Principle state? When stress is applied to a system, the system will try to relieve the stress.

Le Chatelier's 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.

The conditions of a chemical system in equilibrium can change. Le Chatlier's principle says a system at equilibrium responds to changes in predictable ways. The response to a change always occur in a direction that reestablishes equilibrium. And the response to a change always opposes the change to the system.

Le Châtelier's principle states that when a system at equilibrium is subjected to a change in conditions, it will respond by shifting in a way that helps counteract the change and restore equilibrium. In other words, the equilibrium position of a reaction will shift in order to reduce the effect of the imposed change.

General statements of Le Chatelier's principle

It states that changes in the temperature, pressure, volume, or concentration of a system will result in predictable and opposing changes in the system in order to achieve a new equilibrium state.

Le Chatelier's Principle helps to predict what effect a change in temperature, concentration or pressure will have on the position of the equilibrium in a chemical reaction. This is very important, particularly in industrial applications, where yields must be accurately predicted and maximised.

His most important discovery, Le Chatelier's principle, was made in 1884. This simply states that any change made in a system of equilibrium results in a shift of the equilibrium in the direction that minimizes the change.

Many industrial processes use Le Chatelier's principle to help increase yield but often use compromise conditions. These balance high yield with cost and rate of reaction. Methanol, ethanol, sulphuric acid and ammonia production are all examples of reversible reactions in industry that use Le Chatelier's principle.
