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.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
