Concepts and reason
Chemical equilibrium: In a chemical reaction, when the rate of the forward reaction is equal to the rate of the backward reaction, equilibrium is said to have been attained. The concentration of the reactant and product were maintained in the chemical equilibrium.
Equilibrium constant in terms of 
: Equilibrium constant is defined as the ratio of the concentration of the product and the concentrations of reactants, raised to their respective stoichiometric powers.
For the gaseous reactant and product the equilibrium can be expressed in terms of partial pressure, Then equilibrium constant will be 
.
Reaction quotient: Reaction quotient is the ratio of the initial concentrations of reactants to the initial concentrations of products.
Fundamentals
Equilibrium constant: Equilibrium constant is the ratio of the rate constant of a forward reaction to the rate constant of a reverse reaction.
The net equilibrium constant of the reaction 
can be written as
