Elementary vs Non-Elementary Reactions
Inside this lesson
- Define an elementary reaction step and its rate law
- Explain why overall (non-elementary) reactions cannot generally use stoichiometry to write a rate law
- Compute rates using a fractional-order experimental rate law
- Recognize that mechanisms can produce non-integer or even negative orders
