Chlorine monoxide (CIO) 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:
2C10 (g) Clz (g) + Oz (g)
The kinetics of this reaction were studied in a laboratory experiment at 298K, and the data are shown in the table below
(a) Determine the order of the reaction
(b) Determine the rate law expression
(c) Determine the value of the rate constant, k, at 298K.
