a.

Summary Introduction

To classify:

The given reaction as exothermic or endothermic.

Introduction:

The equilibrium constant is a parameter which describes the relationship between concentration of the reactants and the products at equilibrium stage. Equilibrium constant of a reaction is expressed by the ratio of concentration of product species raised to the power of their stoichiometric coefficients to the concentration of reactant species raised to the power of their stoichiometric coefficients.

According to the Le Chatelier’s principle the change in concentration, volume, pressure and temperature affects the equilibrium constant of the reaction.
