Classification of Chemical Equilibrium
In our daily life, we see many things which show incredible balance
Like balancing of stones
Or like weighing scale which is used to weigh fruits and vegetables.
This balancing condition is also known as Equilibrium
Equilibrium is normally of two types viz. Physical equilibrium and Chemical equilibrium
It is a state in which the rate of the forward reaction equals the rate of the backward reaction
In other words, there is no net change in concentrations of reactants and products
Chemical Equilibrium can be further classified on the basis of the state of reactants and products
These are Homogenous equilibrium and Heterogenous equilibrium
'Homogenous' means same and 'Heterogenous' means different
Let's first start with Homogenous equilibrium
In homogeneous equilibrium, the phase of all the reagents (reactants and products) are same
For example, in preparation of ammonia, the state of reactants and products are the same.
Or take an example of the preparation of
So in Homogenous equilibrium the reactant and product have the same state
Now let's move on to Heterogenous equilibrium
In heterogeneous equilibrium, the phases of the reagents are different
For example, the given reaction is in heterogeneous equilibrium as reactant and products are in different states.
Chemical Equilibrium is a state at which the rate of the forward reaction equals the rate of the backward reaction
Chemical Equilibrium can be classified on the basis of phase or state
On the basis of the phase of the reagents, it can be classified as homogeneous equilibrium and heterogeneous equilibrium
In homogeneous equilibrium, the phase of all the reagents (reactants and products) is same
While in heterogeneous equilibrium, the phases of the reagents are different
