Le Chatelier Principle

Front

What is Le Chatelier's Principle?

Back

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.

Front

What happens to the equilibrium position if the concentration of reactants is increased?

Back

The equilibrium position shifts to the right, favoring the formation of products.

Front

What is a forward reaction?

Back

The reaction that forms products from reactants.

Front

What is the definition of equilibrium in a chemical reaction?

Back

Equilibrium is the state in which the rates of the forward and reverse reactions are equal, and the concentrations of reactants and products remain constant.

Front

How does temperature affect the position of equilibrium?

Back

Changing the temperature can shift the equilibrium position; for exothermic reactions, increasing temperature shifts it to the left, while for endothermic reactions, it shifts to the right.

Front

What is the effect of decreasing the volume of a gas reaction at equilibrium?

Back

The equilibrium will shift towards the side with fewer moles of gas to counteract the change.

Front

What is a reactant?

Back

A reactant is a substance that takes part in and undergoes change in a chemical reaction.

Front

What is a product in a chemical reaction?

Back

A product is a substance that is formed as a result of a chemical reaction.

Front

How can the concentration of a product be increased in a reaction at equilibrium?

Back

By increasing the concentration of the reactants or removing some of the products.

Front

What does it mean for a reaction to be at dynamic equilibrium?

Back

It means that the forward and reverse reactions are occurring at the same rate, resulting in constant concentrations of reactants and products.
