Equilibrium 2020

Front

What is equilibrium in a chemical reaction?

Back

Equilibrium is the state in which the concentrations of reactants and products remain constant over time, indicating that the forward and reverse reactions occur at the same rate.

Front

What happens to equilibrium when a reactant is removed?

Back

The equilibrium shifts to the left, favoring the formation of reactants.

Front

What happens to equilibrium when a product is added?

Back

The equilibrium shifts to the left, favoring the formation of reactants.

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.

What happens to equilibrium when heat is added to an exothermic reaction?

Back

The equilibrium shifts to the left, favoring the reactants.

Front

What happens to equilibrium when heat is removed from an exothermic reaction?

Back

The equilibrium shifts to the right, favoring the products.

Front

What happens to equilibrium when a drying agent is added?

Back

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

Front

What is the effect of pressure on equilibrium in gaseous reactions?

Back

Increasing pressure shifts the equilibrium towards the side with fewer moles of gas.

Front

What happens to equilibrium when a catalyst is added?

Back

A catalyst does not affect the position of equilibrium; it only speeds up the rate at which equilibrium is reached.

Front

What is the effect of concentration changes on equilibrium?

Back

Changing the concentration of reactants or products will shift the equilibrium to restore balance.
