Reaction which proceeds in both directions is called_______________?
Correct answer: A. reversible
- A. reversible
- B. irreversible
- C. spontaneous
- D. non-spontaneous
Explanation
A reversible reaction can proceed in both the forward and backward directions, so reactants form products while products can reform reactants. The likely mistaken choice is irreversible, which describes a reaction that is treated as proceeding only in one direction.

About Reversible Reactions
A reversible reaction proceeds in both forward and backward directions, so reactants and products continue changing until dynamic equilibrium is established. The topic covers the meaning of equilibrium, the equality of forward and reverse rates, and how concentration, pressure and temperature disturb equilibrium, which is separate from the rate at which equilibrium is reached.
