Question

Chlorine monoxide accumulates in the stratosphere above Antarctica each winter and plays a key role in the formation of the ozone hole above the South Pole each spring. Eventually, ClO decomposes according to the equation: 2ClO(g) --> Cl2​(g)+O2​(g) The second-order rate constant for the decomposition of ClO is 7.33×109 M–1s–1 at a particular temperature. Determine the half-life of ClO when its initial concentration is 1.11×10-8 M .
