# Write the equilibrium expression (Kp) for each reaction in Exercise 21.

(a)

Interpretation Introduction

Interpretation: The equilibrium expression (Kp) for each of the given gas-phase reactions is to be stated.

Concept introduction: The state when the reactants involved in a chemical reaction and the products formed in the reaction exist in concentrations having no further tendency to change is known as an equilibrium state of the reaction. When the equilibrium constant is expressed in terms of pressure, it is represented as Kp .

To determine: The equilibrium expression (Kp) for the given reaction.

Explanation

Given

The stated reaction is,

N2(g)+O2(g)2NO(g)

At equilibrium, the equilibrium ratio is expressed by the formula,

Kp=PartialpressureofproductsPartial
