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.

The time taken for the statue to break down depends on the reaction rate.  The low concentration of acids in acid rain reduces the reaction rate and increases the time required to break down the statue.  Intricate carvings increase the surface area of the statue and therefore increase the rate of the statue’s breakdown.

I just took the ed-genuity lesson

Hope this helps!

the answer is definitely c.
