A large deep lake, which initially had a uniform oxygen concentration of 1 kg/m3, has its surface concentration suddenly raised and maintained at a 9 kg/m3 concentration level. Reduce the general differential equation for mass transfer to write the specific differential equation for (a) the transfer of oxygen into the lake without the presence of chemical reaction. (b) the transfer of oxygen into the lake that occurs with the simultaneous disappearance of oxygen by a first-order biological reaction.
