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...

2. BigMoney Inc. has also had a major spill of inorganic Fe that contaminated the soil around their plant. Scientists at BigMoney have developed mechanisms for removing Fe from soil, but have not found one for Fe. They want to know, on a strictly theoretical basis (regardless of whether bacteria exist im nature that actually.do these specific reactions) f there are any types of bacteria a. Is this an oxidation or reduction? (0.5 point) b. Is Fe acting as an...
