1
Q

Open system

A

continuously interacts with its environment

2
Q

Closed system

A

isolated by its surroundings

3
Q

Reversible reaction

A

reaction where products can be converted back to reactants

4
Q

Chemical equilibrium

A

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

5
Q

Le charteliers principle

A

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
Q

Eutrophication

A

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.
