Interpretation Introduction

Interpretation:

Equilibrium constant expression for the given reactionshould be identified.

Concept introduction:

Equilibrium is the condition at which the rate of formation of product is equal to rate of disappearance of reactant.

Equilibrium constant is the concentration of product raise to its stochiometric coefficient divided to the concentration of reactant raise to its stochiometric coefficient, pure solids and liquids are not included in the equilibrium constant expression.
