Six lessons cover this chapter, one for each section. Open any of them on its own below, or meet it in place inside chapter 12 of the book. Tick a lesson off once you can predict what it will do before you touch it.

1

Reaction rates

Track concentration against time and read the rate off the curve.

2

Rate laws and reaction order

Run initial-rate experiments and solve for the order.

3

Integrated rate laws and half-life

Plot the three straight-line forms and find the order.

4

Collision theory and activation energy

Collide molecules with the right energy and the right angle.

5

Temperature and the Arrhenius equation

Raise the temperature and watch k climb.

6

Mechanisms and catalysis

Step through a mechanism and lower the barrier with a catalyst.
