Which statement describes a chemical reaction at equilibrium?(1) The products are completely consumed in the reaction.

(2) The reactants are completely consumed in the reaction.(3) The concentrations of the products and reactants are equal.(4) The concentrations of the products and reactants are constant.

Verified Answer :

Answer: Option (3) is the correct answer.

Explanation:

An equilibrium reaction is a reaction in which the concentration of both reactant and products is the same.

That is, the rate of forward reaction is equal to the rate of backward reaction.

For example, \(2SO_{2}(g) + O_{2}(g) \rightleftharpoons 2SO_{3}(g)\)

Thus, we can conclude that out of the given options, statement the concentrations of the products and reactants are equal, describes a chemical reaction at equilibrium.

Answer:

see below

Explanation:

1. The rate of the forward and backward reactions are equal.

2. No changes will be apparent, as the forward and reverse reactions continue.

3. The reactions that happen in baking are not reversible reactions.

4. The reaction mixture is not complete as reactants are still being added to the system.
