Chapter 18, Problem 70AE

Interpretation Introduction

Interpretation:

An explanation for increase in the equilibrium constant for the formation of $\text{NO}$ from ${\text{N}}_{\text{2}}$ and ${\text{O}}_{\text{2}}$ with increasing temperature and decrease in equilibrium constant for the formation of ${\text{NO}}_2$ from $\text{NO}$ and ${\text{O}}_{\text{2}}$ with increasing temperature is to be stated.

Concept introduction: The equilibrium constant of endothermic reaction shifts in forward direction with increase in temperature whereas equilibrium constant of exothermic reaction shifts in backward direction with increase in temperature.

To determine: An explanation for increase in the equilibrium constant for the formation of $\text{NO}$ from ${\text{N}}_{\text{2}}$ and ${\text{O}}_{\text{2}}$ with increasing temperature and decrease in equilibrium constant for the formation of ${\text{NO}}_2$ from $\text{NO}$ and ${\text{O}}_{\text{2}}$ with increasing temperature.
