Question

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.

Explanation:

Reaction rate depends on acid - concentration and surface - area. Concentrated acids have higher reaction rates. Intricate carvings increase surface - area, accelerating breakdown.

Answer:

Acid concentration affects reaction rate. Concentrated acids react faster. Statues with intricate carvings have larger surface - area exposed to acid rain, so they break down more quickly.
