Problem
Nitrogen fixation in the environment is mediated by a bacteria called nitrobacter. The conversion of N2 to NH4+ in nature is the primary reduction reaction at pH 7. This is accompanied by the oxidation of natural organic matter (designated CH2O) to CO2. What are the free energy changes for the two half reactions? What is the total free energy of the redox process? How is the reaction affected in a slightly acidic lake water (pH = 6)?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
