Respuesta :
The correct answer for the question that is being presented above is this one: "2. are equal to the concentrations of the products." Given the reaction: HC2H3O2(aq) + H2O ↔ H3O+(aq) + C2H3O2-(aq) When the reaction reaches a state of equilibrium, the concentration of product is equal yo the reactant.
Answer:
4
Explanation:
The concentration of a solid or a liquid is essentially constant at equilibrium, because the forward and reverse reaction rates are equal.
