Below are the paired reduction reactions for chemolithotrophic denitrification: theseorganisms are using nitrate as an electron accepter and are using hydrogen gas as a source of energy and electrons.
2NO3- + 10e- -> N2 (+0.74 volts)
2H+ + 2e- -> H2 (-0.42 volts)
Using the information given, calculate the ΔE for this reaction, balance the full reaction to determine n, the number of electrons transfered when 53 molecules of H2 are oxidized. Finally, use the simplified Nernst Equation
ΔG = -nFΔE, where F = 96.48 kJ (mol e-)
to determine the Gibbs Free energy available to do work!
