Question

At equilibrium, a balanced reaction should be written with a double arrow between the reactants and the products, a generic would be written:

aA + bB ? cC + dD

Which side represents the reactants and what is implied by the double arrow in the balanced reaction?

A) The reactants are on the right, the double arrow means the forward and reverse reaction rates are equal.

B) The reactants are on the left, the double arrow means the forward and reverse reaction rates are equal.

C) The reactants are on both sides, the double arrow means the reactants and products are changing sides.

D) None of the other answers are applicable.

A) The reactants are on the right, the double arrow means the forward and reverse reaction rates are equal.

B) The reactants are on the left, the double arrow means the forward and reverse reaction rates are equal.

C) The reactants are on both sides, the double arrow means the reactants and products are changing sides.

D) None of the other answers are applicable.

The answer is B, usually the reactants are on the left, the arrow represent a dynamic equilibrium, where reactions rates are equal.
