Reversible reactions and dynamic equilibrium
Question
- A. products can react again to remake the original reactants
- B. reactants disappear and can never reform
- C. only gases can react reversibly
- D. the reaction always releases heat
Answer
products can react again to remake the original reactants. That is the defining feature of a reversible reaction.
Explanation
products can react again to remake the original reactants is correct because reversible reactions can proceed in both forward and reverse directions. The other options add restrictions that are not part of the definition.
Common mistake
Misunderstanding Reversible Reactions
Students often think that reversible reactions only go in one direction and do not understand that products can react to form the original reactants.
To fix this, students should remember that in a reversible reaction, the products can react to regenerate the reactants, illustrating the dynamic nature of these reactions.
