Question

What is true of a reaction that has reached equilibrium?

a.the reaction rates of the forward and revers reactions are equal.
b. the rate of the forward reaction i sgreater than the rate of the reverse reaction
c. the reactio rate is zero
d. the rate of the forward reaction is less than the rate of the revers reaction?

Answer 1

I believe the correct answer from the choices listed above is option A. A reaction that has reached equilibrium would mean that the reaction rates of the forward and reverse reactions are equal. Hope this answers the question. Have a nice day.

Answer 2

The correct option is A.

A chemical reaction is said to have reached an equilibrium stage if the rate of reaction of the forward reaction is equal to the rate of reaction of the reverse reaction. Two way arrows are usually used to depict equilibrium reactions. These arrows indicate that the chemical reaction can move both ways. At the equilibrium point the concentrations of both the reactants and the products are equal.
