In order to understand chemical reactions, you are going to have to come to terms with an important concept, that is, chemical equilibrium.
In AUS-e-TUTE's new set of resources (tutorial, game, test and exam questions with worked solutions) we look at how the type of system (open or closed) and the type of reaction (reversible or irreversible) determines whether a system can achieve a state of balance otherwise known as chemical equilibrium.
AUS-e-TUTE members should log-in to use these new resources.
