What happens to a chemical reaction when it is in equilibrium?

In a chemical equilibrium, the forward and reverse reactions occur at equal rates, and the concentrations of products and reactants remain constant. A catalyst speeds up the rate of a chemical reaction, but has no effect upon the equilibrium position for that reaction.

What happens in a reaction if it is at chemical equilibrium quizlet?

What happens in a reaction if it is at chemical equilibrium? The rate of the forward reaction equals the rate of the reverse reaction.

What happens when equilibrium is disturbed?

When a chemical system at equilibrium is disturbed, it returns to equilibrium by counteracting the disturbance. As described in the previous paragraph, the disturbance causes a change in Q; the reaction will shift to re-establish Q=K.

What is chemical equilibrium quizlet?

Chemical Equilibrium. A state in which the rates of forward and reverse reactions are the same. An active, dynamic condition, not static. All substances are being made & unmade at the same rate, so their concentrations are constant. Not necessary for products and reactants to be equal.

How is chemical equilibrium achieved quizlet?

When is equilibrium reached? When, in a closed system, the rates of the forward and reverse reactions are occurring in equal rates and there is no change in concentration of reactants and products.

When an equilibrium shifts to the right what happens to each of the following?

Equilibrium shifts to the right. That is, when a new equilibrium is reached (when the rate of forward and reverse reactions are equal again), there will be more product than before. When the concentration of reactants is increased, the equilibrium shifts to the right and there will be more product than before.

What happens to a reaction at equilibrium when the concentration of the products is increased?

If the concentration of a substance is increased, the reaction that consumes that substance is favored, and the equilibrium shifts away from that substance. If the concentration of a substance is decreased, the reaction that produces that substance is favored, and the equilibrium shifts toward that substance.

How do you know if a reaction is at equilibrium quizlet?

When a reaction reaches equilibrium, it appears as if nothing is happening because it is balanced. Two opposing processes that occur at the same rate. The point at which the rate of the forward reaction is equal to the rate of the reverse reaction.

What is meant by chemical equilibrium expression?

chemical equilibrium, condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs. At equilibrium, the two opposing reactions go on at equal rates, or velocities, and hence there is no net change in the amounts of substances involved.
