- C. 1:2
- D. 0:1
Answer
1:1
Explanation
The correct answer is 1:1. This answer directly addresses the question: In a reversible reaction at equilibrium, if the concentration of reactants is 0.5 mol/dm3 and the concentration of products is 0.5 mol/dm3, what is the ratio of reactants to products? It matches the approved Chemistry 8462 learning objective and the linked subtopic. The other options are incorrect because they either change the rate, catalyst, reversible reaction, equilibrium, or graph context, or they do not answer the exact point being tested.
Common mistake
Misunderstanding Equilibrium Concentrations
Students often think that the concentrations of reactants and products are equal at equilibrium.
Emphasize that at equilibrium, the concentrations remain constant but are not necessarily equal.
