Explain the compound 4-amino benzoic acid C7H7NO2 is oxidized by oxygen to carbon dioxide, nitrogen dioxide, and water. Suppose you have one mole of the 4-amino benzoic acid and a stoichiometric amount of oxygen, Explain how long will the system produce 15.00 amperes of current and what is the Grxn for this reaction if the resistance is 0.08750 ohms? The Faraday constant is 96485.3C/mole of electrons; V=I*R, the reduction reaction of O2 is O2 + 4H+ + 4e--> 2H2O.
