What happens to the equilibrium when the volume of a system is increased?

Back

The equilibrium shifts left.

Front

What happens to the equilibrium when more H2O is added to the system?

Back

The equilibrium shifts left.

Front

What is the effect on equilibrium when a portion of CO2 is removed?

Back

The equilibrium shifts left.

Front

What happens to the equilibrium when a drying agent is added?

Back

The equilibrium shifts right.

Front

Define equilibrium in a chemical reaction.

Back

Equilibrium is the state in which the concentrations of reactants and products remain constant over time.

Front

What is Le Chatelier's Principle?

Back

Le Chatelier's Principle states that if a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change.

Front

How does increasing pressure affect equilibrium?

Back

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

Front

What is the effect of temperature on exothermic reactions at equilibrium?

Back

Increasing temperature shifts the equilibrium to the left, favoring the reactants.

Front

What is the effect of temperature on endothermic reactions at equilibrium?

Back

Increasing temperature shifts the equilibrium to the right, favoring the products.

Front

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

Back

Dynamic equilibrium means that the rate of the forward reaction equals the rate of the reverse reaction.
