Some bacteria can use nitrate as an electron acceptor instead of oxygen, reducing it to nitrite. This requires an enzyme called nitrate reductase. The reduction and oxidation redox equations I am using are: NO3- +2H+ +2e- ---> NO2- + H2O NAD+ + 2H+ +2e- ---> NADH + H+ I calculated the Gibbs free energy change under standard state conditions for the oxidation of NADH by nitrate to be -144.75 kJ/mol. Please use the value to help solve part a. Please...
