Chapter 25, Problem 56E

Interpretation Introduction

Interpretation: The equilibrium constant for the following reaction is to be determined. On the value of equilibrium constant, it is o be determined whether the equilibrium favor the reactants or products.

${\text{HbO}}_2+{\text{CO}}_2\rightleftharpoons \text{HbCO}+{\text{O}}_2$

Concept Introduction:

On reversing the equation, the equilibrium constant is inverted.

On adding the equations, their equilibrium constants get multiplied in order to obtain the overall equilibrium constant for the desired reaction.

When the value of equilibrium constant is smaller than 1 i.e. $K<1$, equilibrium favors the formation of reactants i.e. backward reaction is favored. But when $K>1$, equilibrium favors the formation of products i.e. forward reaction is favored.
