The following data were obtained for the reaction:
2NO + O2 → 2NO2
|Experiment||[NO]/M||[O]2/M||Initial rate of formation of NO2/M min-1|
|1||0.3||0.2||7.2 x 10-2|
|2||0.1||0.1||6.0 x 10-3|
|3||0.3||0.4||2.88 x 10-1|
|4||0.4||0.1||2.40 x 10-2|
(i) Find the order of reaction with respect to NO and O2.
(ii) Write the rate law and overall order of reaction.
(iii) Calculate the rate constant (k).
