# Which of the following best describes a reaction at equilibrium?

## Which of the following best describes a reaction at equilibrium?

Which of the following best describes a chemical reaction in a state of equilibrium? The rates of the forward and reverse reactions are equal. The concentrations of the reactants equal the concentrations of the products.

What describes a reaction at equilibrium?

In a chemical reaction, chemical equilibrium is the state in which the forward reaction rate and the reverse reaction rate are equal. The result of this equilibrium is that the concentrations of the reactants and the products do not change.

### What is true about reactants and products at equilibrium?

If the reactants and products are equal in energy, at equilibrium, they will have the same concentration. If the products are lower in energy, there will be a higher % of the products in the equilibrium mixture. If the reactants are lower in energy, there will be a higher % of the reactants in the equilibrium mixture.

How do you tell if reactants or products are favored at equilibrium?

The equilibrium constant expression is a mathematical relationship that shows how the concentrations of the products vary with the concentration of the reactants. If the value of K is greater than 1, the products in the reaction are favored. If the value of K is less than 1, the reactants in the reaction are favored.

#### What statement best describes general equilibrium?

At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. As defined, the rate of the forward reaction is equal to the rate of the reverse reaction.

Which statement is the best definition of chemical equilibrium?

The definition of chemical equilibrium is the point at which the concentrations of reactants and products do not change with time. It appears as though the reaction has stopped but in fact the rates of the forward and reverse reactions are equal so reactants and products are being created at the same rate.

## How do you shift the equilibrium of a reaction?

One way is to add or remove a product or a reactant in a chemical reaction at equilibrium. When additional reactant is added, the equilibrium shifts to reduce this stress: it makes more product. When additional product is added, the equilibrium shifts to reactants to reduce the stress.

Which statement most accurately describes the behavior of a catalyst?

Question: Question 22 (1 point) Which statement most accurately describes the behavior of a catalyst? O A catalyst increases AG of a reaction and hence the forward rate. A catalyst reduces the AH of a reaction and hence the temperature needed to produce products.

### What are new substances produced by a chemical reaction?

New substances produced by a chemical reaction are _______. products The law of conservation of mass states that _______. in a chemical reaction, matter is not crated or destroyed, but is conserved Ten grams of mercury(II) oxide react to produce 9.3 g of mercury and oxygen.

Which is the correct formula for a balanced chemical equation?

A chemical equation The following chemical equation is balanced, but its coefficients are larger than necessary. Rewrite this balanced equation using the smallest coefficients possible. 9Fe(s) + 12H2O(l) → 3Fe3O4(s) + 12H2(g) 3Fe(s) + 4H2O(l) → Fe3O4(s) + 4H2(g)

#### What kind of compound comes out of a double displacement reaction?

An insoluble compound that comes out of solution during a double displacement reaction is called a _______. precipitate
