Henry’s Law tells us that in a simple hydrologic system
( a beaker of water?) oxygen concentration will eventually
reach an equilibrium where
[O2] = [saturation] = oxygen solubility * 20.99
If we imagine a very simple ecosystem,
where P and R rates are constant but at some unknown rate, what
expression can you find (based on the mass balance equation)
for the equilibrium [O2]?
Hint: at equilibrium DO2 = d/dt O2 = 0
