Why is the adult respiratory rate lower than an infant's respiratory rate?

Infants have smaller lungs, and although they also have smaller bodies, the smaller lungs must work faster to exchange the amount of gasses, i.e. O2 and CO2, the same way their hearts beat faster than an adult's to pump the amount of blood they need because of it's small size.
