Exam 20: Chemistry in the Atmosphere

The average person breathes about 20 m³ of air a day. What mass of particulates would a person breathe in a day if the particulate level were 400 micrograms per cubic meter

The rate constant of the reaction Cl + CHCl₃ $\rarr$ HCl + CCl₃ is 5.8 *10⁷ M^-1s^-1 at 25 ^$\circ$ C and has an activation energy of 11.0 kJ/mol. Calculate the rate constant for this reaction in the lower stratosphere where the temperature is -57 ^$\circ$ C.

The compound CFCl₃ is used as a/an

The steps in the mechanism by which ozone is formed in the stratosphere are shown here: O₂(g) + O $\rarr$ 2O(g) O(g) + O₂(g) $\rarr$ O₃(g)

Acid rain is precipitation having a pH that is

The balanced chemical equation for the reaction of acid rain with limestone rock is shown here: CaCO₃ + 2H⁺ $\rarr$ Ca²⁺ + CO₂ + H₂O
