For the decomposition of nitrous oxide at 565 °C

2 N2O2 N2 + O2

the following data have been obtained:

 [N2O], M 1.83 0.946 0.638 0.481 time, s 0 7.73 15.5 23.2

The average rate of disappearance of N2O over the time period from t = 7.73 s to t = 15.5 s is  M s-1.

Step 1

The rate of a reaction is expressed as : Step 2

The given reaction and the data table are : At t = 7.73 s, [N2O] = 0.946 M

At t = 15.5 s, [N2O] = 0.638 M

Step 3

Therefore, the average rate of disappearance of N2O over the time period from t = 7.73 s to t = 15.5 s can be calculate as : ...
