The lessons in order
| Ref | Lesson pack | Structure | Worksheet | Quiz | Lab tab |
|---|---|---|---|---|---|
| 26.1 | Orders of reaction and rate equations A rate equation says exactly how the rate responds when you change each concentration. | Numbered Heads Together | 6 Q, 16 marks | 8 MCQ | tab 1, tab 2 |
| 26.1 | Rate-determining step and mechanisms Most reactions happen in a series of steps, and the overall rate can be no faster than the slowest one. | Corners | 6 Q, 15 marks | 8 MCQ | tab 3 |
| 26.2 | Temperature, rate constants and the Arrhenius equation Changing concentration changes the rate but not k. | Rally Coach | 6 Q, 15 marks | 8 MCQ | tab 4, tab 5 |
| 26.3 | Homogeneous and heterogeneous catalysts A catalyst does not just lower a hump on a diagram: it opens up a new mechanism. | Quiz-Quiz-Trade | 6 Q, 15 marks | 8 MCQ | tab 6 |
Each pack holds the plan, worksheet and quiz for its lesson. Teach the rows in order; the lab tabs match the student lessons.
