A large deep lake, which initially had a uniform oxygen concentration, has its surface concentration suddenly raised and maintained at a higher concentration level. Assuming the lake water to be static, reduce the general differential equation for mass transfer to write the specific differential equation using the diffusivity of O₂ (A) through water (B), D_AB, for:

a) the transfer of oxygen into the lake without the presence of a chemical reaction. State all assumptions.

b) the transfer of oxygen into the lake that occurs with the simultaneous disappearance of oxygen by a first-order biological reaction with a rate constant k (> 0).
