Below are the paired reduction reactions for chemolithotrophic denitrification: these organisms are using nitrate as an...

Below are the paired reduction reactions for chemolithotrophic denitrification: these organisms 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 97 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!

Report your answer in kJ per mole rounded to two decimal places.
Report only the numeric portion of your answer
- e.g. 1.01, not 1.01 kj per mole.
Answers should ALWAYS be negative since this is a spontaneous reaction.
