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, CIO decomposes according to the equation: 2CIO(g) --> C12(g)+O2(g) The second-order rate constant for the decomposition of CIO is 7.33109 M-1s-1 at a particular temperature. Determine the half-life of CIO when its initial concentration is 1.1610- 8 M.
