Equilibrium
Definition
-
Neither reactions have stopped, both are reacting at the same speed.
-
“At equilibrium the concentrations of the reactants and products are constant but not necessarily equal.” (BBC Bitesize)
Dynamic equilibrium
-
When the rate of the forward reaction is the same as the reverse reaction, the reaction is said to have reached equilibrium.
If a catalyst where to be used, the reaction would reach equilibrium much sooner.
Shifting equilibrium
If we make changes to the concentration, pressure or temperature of the reaction then the position of the equilibrium can be altered.
Any change made to a reaction which is in equilibrium, will result in the equilibrium position moving to minimize the change made
E.g. changing the concentration
The following equilibrium is formed when chlorine dissolves in water:
-
-
Open and closed systems
-
Closed systems
A closed system is when a reaction happens in a closed environment (such as a container), meaning that none of the reactants or products can escape.
-
Le Chatelier's Principle
-
Whenever a system in equilibrium is disturbed the system will adjust itself in such a way that the effect of the change will be nullified.
