Interpretation Introduction

(a)

Interpretation:

The equilibrium expression for the given reaction is to be stated.

Concept Introduction:

The equilibrium constant of a reaction is expressed as the ratio of concentration of products and reactants each raised to the power of their stoichiometric coefficients. A general equilibrium reaction is represented as,

aA+bBcC+dD

The equilibrium constant for the above chemical reaction is expressed as,

K=[C]c[D]d[A]a[B]b

Where,

• [A] represents the equilibrium concentration of reactant A.
• [B] represents the equilibrium concentration of reactant B.
