Integrated rate law half life sample problems
The rate of the reaction O + NO2 ----------> NO + O2 was studied at a certain temperature.
|0||5.0 x 109|
|1.0 x 10-2||1.9 x 109|
|2.0 x 10-2||6.8 x 108|
|3.0 x 10-2||2.5 x 108|
1) In the first set of experiments, NO2 was in large excess at a concentration of 1.0 x 1013 molecules/cm3with the following data collected above in the table.
1a) what is the order of the reaction with respect to oxygen atoms?
2) The reaction is known to be first order with respect to NO2 . determine the overall rate law and the law and the value of the rate constant?
