2NO + 2H 2 
N 2 + 2H 2 O
The above reaction has been studied at 800°C. The related data are given in the table below
Reaction serial number | Initial pressure of H2/ kPa | Initial Pressure of NO/ kPa | Initial rate |
1 | 65.6 | 40.0 | 0.135 |
2 | 65.6 | 20.1 | 0.033 |
3 | 38.6 | 65.6 | 0.214 |
4 | 19.2 | 65.6 | 0.106 |
The order of the reaction with respect to NO is____
Text Solution
Verified by ExpertsThe correct answer is:
2
(2)
On decreasing pressure of NO by a factor of '2' the rate of reaction decreases by a factor of '4'
Order of reaction w.r.t. 'NO' = 2
