Six lessons cover this chapter, one for each section. Open any of them on its own below, or meet it in place inside chapter 13 of the book. Tick a lesson off once you can predict what it will do before you touch it.

1

Dynamic equilibrium

Watch forward and reverse rates meet and hold.

2

The equilibrium constant

Write K from an equation and see what big and small K mean.

3

The reaction quotient Q

Compare Q with K and predict which way the reaction shifts.

4

Le Chatelier's principle

Add, remove, squeeze and heat a system at equilibrium.

5

ICE tables

Fill an ICE table and solve for the equilibrium amounts.

6

Equilibrium calculations

Work through K problems, including the small-x shortcut.
