Expert Solution

Introduction :

Equilibrium constant :

This is defined for reaction which are present in equilibrium form and it can be calculated by dividing concentration of the products which is raised to power of stoichiometric coefficients with concentration of reactants which is again raised to power of stoichiometric coefficients.

It is denoted by " K_eq".

Also, Equilibrium constant helps in deciding whether reaction will be reactant favored or product favored .

Calculation :

The given reaction is :
