Chapter 13.5, Problem 40PP

Use the following equation for the equilibrium of hemoglobin in the blood to answer problems 13.39 to 13.42:
$\text{Hb}(aq)+{\text{O}}_2(g)\rightleftarrows {\text{HbO}}_2(aq)$
c. decreasing $[\text{HD}]$
13.40 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. decreasing $\left[{\text{O}}_2\right]$
b. increasing $[\text{Hb}]$
c. decreasing $\left[{\text{HbO}}_2\right]$
