Pre LectureDynamic Equilibrium
At a certain point all ruins are reversiable
When the speed of forward and reverse reactions are equal
o so the concentrations of the reactants or products remain constant
then equilibrium is attained
rate of forward reaction rate of reverse reaction
The concept of Equilibrium
Physical equilibrium consists of a single substance
T
Ex Azole Hz0cg
Chemical equilibrium involves 2 or more substances
Ex Nz04cg F 2N02cg
for equilibrium we write A E B
As the rum progresses i
1 A decreases to a constant
2 B increases from 0 to a constant
3 When Ar B are constant equilibrium is achieved
Kfwd key
Krev
, The magnitude of K
K is ratio of products to reactants measure of reaction extent
Small k very little product mostly reactant no rxn
Large K mostly product very little reactant Gemgoes to completion
Intermediate k significantamount of product r reactant

Manipulating Equilibrium Constants
when we multiply a balanced equation
by n then we raise the
value of K to the power of n
