Chemical Equilibrium

Front

What is chemical equilibrium?

Back

Chemical equilibrium is a state in a reversible reaction where the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.

What does Le Châtelier’s principle state?

Back

Le Châtelier’s principle states that if a stress is applied to a system at equilibrium, the system will shift in the direction that relieves the stress.

Front

What happens to equilibrium when the concentration of a product is increased?

Back

The equilibrium will shift to the left, favoring the formation of reactants.

Front

What is the effect of adding heat to an exothermic reaction at equilibrium?

Back

Adding heat to an exothermic reaction will shift the equilibrium to the left, favoring the reactants.

Front

What is the effect of increasing the concentration of a reactant on equilibrium?

Back

Increasing the concentration of a reactant will shift the equilibrium to the right, favoring the formation of products.

Front

Define dynamic equilibrium.

Back

Dynamic equilibrium is a condition in which the forward and reverse reactions continue to occur at equal rates, resulting in no net change in the concentrations of reactants and products.

Front

What is a reversible reaction?

Back

A reversible reaction is a chemical reaction where the products can react to form the original reactants.

Front

What is the equilibrium constant (K)?

Back

The equilibrium constant (K) is a numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium, each raised to the power of their coefficients in the balanced equation.

Front

What does it mean if K > 1?

Back

If K > 1, it indicates that at equilibrium, the concentration of products is greater than that of reactants.

Front

What does it mean if K < 1?

Back

If K < 1, it indicates that at equilibrium, the concentration of reactants is greater than that of products.
