| Second Order Reaction |
|
| Example 6: |
| |
| Nitrogen dioxide (NO2) gas reacts with fluorine gas (F2) to give nitrosyl fluoride. The chemical reaction is given by the equation. |
| |
 |
| |
| The reaction has the rate law as: |
| |
| rate (r) = k [NO2] [F2] |
| |
| The rate has order one with respect to nitrogen dioxide concentration and fluorine concentration and the overall order is (1 + 1) which is two. |
