*Equilibrium*
Dynamic
equilibrium
is the balanced state that a reversible
reaction
naturally reaches.
Right
Hand Side, Forward reaction
A
+ B ⇄
C + D
Backward
reaction, Left Hand Side
Le
Chatelier’s Principle:
if external changes are made upon a system, the reaction will move in
the direction to oppose the change and return to it’s original
state of equilibrium.
Factors
affecting the position of equilibrium:
If
temperature
is increased:
the reaction will move to the endothermic side
If
the pressure
is increased:
the reaction will move to the side with fewest moles
If
a substance
is removed:
the reaction will move to the side to make more of it
If
a substance
is added:
the reaction will move to the side which removes it
If
a catalyst
is added,
there is no change on the position of equilibrium. The catalyst
speeds up the rate of both the forward and backward reactions
equally.
