There are many situations when one or more factors have differing effects on a system. Knowledge of equilibria and the factors that can affect it enable chemists to be able to follow a reaction. This knowledge can then be used to affect the position of the equilibrium in order to more effectively develop products. This programme is designed to develop students understanding through basic concepts such as reversible and irreversible reaction, looking at both physical and chemical changes, to dynamic equilibria and factors that affect equilibria. Working through the activities will also develop thinking and research skills.
