Construct the stoichiometric energy generating reaction from the half reactions associated with oxidation of ethanol to CO2 under sulfate reducing conditions.
An underground storage tank has sprung a leak, sending 184 kilograms of ethanol into the
subsurface soil. Ethanol can be used as an electron donor under either aerobic (oxygen is the
electron acceptor) or sulfate reducing (sulfate is reduced to H2S) conditions. a) How many
electrons are transferred during the oxidation of ethanol (C2H5OH) to carbon dioxide (CO2)? b)
Construct the stoichiometric energy generating reaction from the half reactions associated with the
aerobic oxidation of ethanol to CO2. c) Construct the stoichiometric energy generating reaction
from the half reactions associated with oxidation of ethanol to CO2 under sulfate reducing
conditions.
