Which of the following statements is true about a reversible reaction?

Question

Quizplus · Accepted Answer

In a reversible reaction, the reactants can react to form products, and the products can react to form reactants again. This means that when we mix the reactants together, none of them will be completely used up since they can react in both directions. Therefore, option D is the correct choice. Option A is incorrect because the direction of heat flow (exothermic or endothermic) depends on the specific reaction and cannot be generalized for all reversible reactions. Option B is incorrect because although reversible reactions may have low activation energy, it is not a necessary condition for them to be reversible. Option C is also incorrect because in a reversible reaction, the reactants can be converted to products and vice versa, so none of the reactants will be completely used up.
