The One Equation You May Read

You'll learnthat for an elementary step alone, the coefficients equal the rate-law orders.

Topic 5.2 taught you that orders come from experiment and never from the coefficients. This topic is the single exception, it is narrow, and it is the most over-used licence in the unit: an elementary step describes an actual collision, so its coefficients really are its orders. Twelve short steps; press Next for each one.

The question
When are you allowed to read a rate law's exponents straight off the coefficients?
