Question:
The conversion of ethanol to methane is carried out in two separate steps by two different species of bacteria living in a syntrophic (mutual feeding) association, acetogens and methanogens respectively:
Acetogens produce acetate from ethanol in an energetically unfavorable reaction while methanogens produce methane from H2 and CO2 in a highly favorable reaction.
a. Calculate the overall free energy change under standard conditions at 25°C and pH 7, for the coupling of these two reactions (per mole of ethanol).
