Le Chateliers Principle FAQs

What is Le Chatelier’s Principle of Equilibrium?

Le Chatelier’s Principle was proposed by Le Chatelier, a renowned French chemist to describe the effect of change in pressure, temperature, and concentration on any reversible system. In other words, a change in any of the factors that determine the equilibrium conditions of a system will cause the system to change in such a manner to reduce the effect of change....

Effect of Concentration Change on Equilibrium

In chemical equilibrium, increasing the concentrations of the reactants results in shifting the reaction in favor of products so as to oppose the effect of increase of concentration of reactants. Hence, the rate of forward reaction increases. Similarly, increasing the concentrations of the products results in shifting the reaction in favor of reactants so as to oppose the effect of increase of concentration of reactants. Hence, the rate of backward reaction increases....

Effect of Change in Pressure on Equilibrium

In chemical equilibrium, an increase in pressure applied to a system at equilibrium, favors the reaction in the direction that produces lower number of moles of gases and a decrease in pressure favors the opposite reaction. Since, pressure and number of moles are related. The relation between equilibrium constants kp and kc is given by the following formula:...

Effect of Change in Temperature on Equilibrium

According to Le Chatelier’s Principle, the position of equilibrium moves in such a way as to tend to undo the change that we have made. If we increase the temperature, the position of equilibrium will move in such a way as to reduce the temperature again and it will be done by favoring the reaction which absorbs heat. A rise in temperature favors the endothermic reaction as the heat speeds up the rate of reaction by providing sufficient energy to reactant molecules to complete reaction faster....

Effect of Catalyst on Equilibrium

The use of appropriate catalyst will increase the rate of reaction thereby decreasing the time required to reach the equilibrium position. A catalyst can’t change the equilibrium constant Hence, the relative ratio of concentration of reactants and products remain unaffected....

Effect of Addition of an Inert gas on Equilibrium

All the gases which do not participate in reaction are considered as inert gas. The effect of addition of inert gas on equilibrium at different conditions in discussed below:...

Application of Le Chatelier’s Principle

Le Chatelier’s principle is a fundamental concept in chemistry that describes how a system at equilibrium responds to changes in temperature, pressure, or concentration of reactants or products. This principle is applied in various chemical processes and industries to optimize reactions, maximize yields, and control equilibrium conditions. Some key applications of Le Chatelier’s principle include:...
