1

Open system

continuously interacts with its environment

2

Closed system

isolated by its surroundings

3

Reversible reaction

reaction where products can be converted back to reactants

4

Chemical equilibrium

Dynamic equilibrium where the rate of the forward reaction equals the rate of the reverse reaction

5

Le charteliers principle

When equilibrium in a closed system is disturbed, the system will reinstate a new equilibrium by favouring the reaction that will oppose the disturbance.

6

Eutrophication

Process by which an ecosystem (eg. river, dam) becomes enriched with inorganic plant nutrients, especially phosphorus and nitrogen, resulting in excessive plant (algae) growth. As plant growth becomes excessive, the amount of dead and decaying plant material increases rapidly.
