Acid rain is a dilute solution of acids that dissolve the calcium carbonate in limestone statues. Concentrated acids can dissolve a large piece of limestone in a few days. Statue breakdown due to acid rain can take decades, but statues with intricate carvings break down more quickly. Explain these observations in terms of reaction rates.

Answer:

The reaction rate determines how quickly the limestone statue dissolves. Acid rain is a dilute solution, and a lower concentration of reactants results in a slower reaction rate, which is why it takes decades to break down. Conversely, concentrated acids react much faster. Additionally, statues with intricate carvings have a greater surface area exposed to the acid. An increased surface area allows for more collisions between the acid and the calcium carbonate, which increases the reaction rate and causes these statues to break down more quickly.
