For a certain reaction a large fraction ...

For a certain reaction a large fraction of molecules has energy more than the threshold energy, still the rate of reaction is very slow. The possible reason for this could be that

Text Solution

Verified by Experts

This is because colliding molecules may not be having proper orientation for collision to be effective.
