D. Dissolvingsugar in water

Answer

Thermal decomposition of ammonium chloride

Explanation

The correct answer is Thermal decomposition of ammonium chloride. This answer directly addresses the question: Which of the following is an example of a reversible reaction? 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 Reaction Direction

Students often think that changing conditions will always favor the forward reaction in a reversible reaction.

Remember that according to Le Chatelier's Principle, changing conditions can favor either the forward or reverse reaction depending on the specific change made.
