for a certain reactions, large fractions of molecules has energy more than the threshold energy, yet the rate of reaction is very slow. Why? |
| Answer» Solution :Apart from the possessing energy equal to threshold energy `(E^(@))` or more, the reacting species must be property orientation the time of collision. i.e., the atoms of the reacting species which are to ACTUALLY combine must face each other. In the time REACTION under observation, the orientation effect is not proper. Therefore, effective collisions are not as much as EXPECTED. The reaction is therefore, a slow reaction. | |
