Answer:
Explanation:
The equation that models the equilibrium between hemoglobin, oxygen, and oxyhemoglobin is:
     [tex]Hb(aq)+O_2(g)\rightleftharpoons HbO_2(aq)[/tex]
According to LeChatelier's principle, the equilibrium shifts to counteract the the unbalancing action.
As the climbers ascend, the concentration of oxygen, Oâ‚‚(g) decreases, meaning that the reverse reaction will increase, allowing the oxyhemoglobin produce more oxygen. Thus, the equilbrium would shift to the left as the climbers ascend to higher altitudes.
