Ethanol can react with hydrochloric acid to form chloroethane and water. When sulfuric acid is added, the reaction proceeds more quickly. The sulfuric acid is still present when the reaction is complete. Which statement correctly describes this reaction?

A catalyst increases the reaction rate without being used up. Sulfuric acid makes the reaction proceed more quickly and is still present when the reaction is complete, so it acts as a catalyst. Water is a product of the reaction, not a catalyst.
