Which statements are true about reversible reactions?
umka21 [38]

Answer:

Reversible reactions exhibit the same reaction rate for forward and reverse reactions at equilibrium.

Reversible reactions exhibit constant concentrations of reactants and products at equilibrium

Explanation:

A reversible reaction is a reaction that can proceed in both forward and backward direction.

Equilibrium is attained in a chemical system when there is no observable change in the properties of the system.

At equilibrium, a reversible reaction is occurring in at same rate. That is, the forward and backward reaction is occurring at the same rate. As the rate of the forward and backward reaction remains the same, the concentrations of the reactants and products will also be the same in order for the equilibrium to be maintained.
