Question:

The amount absorbed is 0.2(ct - 0.05) if ct ≥ 0.05. This models a case where the only oxygen available is that in excess of the concentration in the blood, which is roughly 5%.
The above problem investigates absorption that is not proportional to the concentration in the lungs. Assume γ = 0.21 and q = 0.1, and find the equilibrium concentration.
