Chapter 13.5, Problem 39PP

Use the following equation for the equilibrium of hemoglobin in the blood to answer problems 13.39 to 13.42:
$\text{Hb}(aq)+{\text{O}}_2(g)\rightleftarrows {\text{HbO}}_2(aq)$
13.39 For the hemoglobin equilibrium, indicate if each of the following changes shifts the equilibrium in the direction of the product, the reactants, or does not change:
a. increasing $\left[{\text{O}}_2\right]$
b. increasing $\left[{\text{HbO}}_2\right]$
c. decreasing [Hb]
