The decomposition of N_(2) O_(5) in "CCI"_4 solution at 318 K has been studied by monitoring the concentration of N_(2) O_(5) in the solution. Initially, the concentration of N_(2) O_(5) is 2.33 M and after 184 minutes, it is reduced to 2.08M. The reaction takes place according to the equation, 2N_(2) O_(5) to 4NO_(2) + O_(2) . Calculate the average rate of this reaction in terms of hours, minutes and seconds. What is the rate of production of NO_2 during this period.
