Question | Answer |
---|---|
Individual order | The power to which a concentration is raised in the rate equation |
Overall order | The sum of all the individual orders in the rate equation. |
rate-determining step | The slowest step in an overall reaction sequence |
Unimolecular steps | reactions that involve a single species as a reactant. |
Bimolecular steps | reactions that involve collisions of two species (that form a transition state or an activated complex that cannot be isolated). |
Intermediate | Reaction species that is stable, exist for a finite time, occur at PE minimum |
Transition state | Reaction species that is unstable, exist for transient time, occur at PE maximum |
