Chemical Equilibrium

Front

What is Chemical Equilibrium?

Back

A state in a chemical reaction where the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.

Front

What is Le Châtelier’s Principle?

Back

If a stress is applied to a system at equilibrium, the system shifts in the direction that relieves the stress.

Front

What does 'dynamic equilibrium' mean?

Back

A state where the forward and reverse reactions occur at the same rate, resulting in constant concentrations of reactants and products.

Front

What happens to equilibrium when the concentration of a reactant is decreased?

Back

The equilibrium shifts to the left to produce more reactants.

Front

What is the effect of removing a product from a reaction at equilibrium?

Back

The equilibrium shifts to the right to produce more products.

Front

What does it mean if the concentrations of reactants and products do not change at equilibrium?

Back

It indicates that the forward and reverse reactions are occurring at the same rate.

Front

What is a common misconception about equilibrium?

Back

That the concentrations of reactants and products are equal; they can be different.

Front

What is the significance of the equilibrium constant (K)?

Back

It quantifies the ratio of concentrations of products to reactants at equilibrium.

Front

How does increasing pressure affect a gaseous equilibrium?

Back

The equilibrium shifts towards the side with fewer moles of gas.

Front

What is a heterogeneous equilibrium?

Back

An equilibrium involving reactants and products in different phases (e.g., solid, liquid, gas).
