Compute the standard potential difference and the standard free energy change when two electrons are transferred from NADPH to NO3, using the half reaction potentials shown below. F=23.06 kcal/V mol, R = 1.987cal/mol K and T = 300 K. Show work, state equation(s) as well as circle answers. Explain what would this process be called? It's common among anaerobic microorganisms.Reduction Half Reaction n Eo'NADP+ ->NADPH 2 - 0.330 voltsNO3 -> NO2 2 +0.421 volts
