The transfer of electrons along the electron transport chain is exergonic.

Calculate the change of free energy associated with the transfer of electrons along the electron transport chain in these bacteria. Use the E$\text{'}\backslash$deg listed in the table below, and assume that the Faraday constant is $96\mathrm{.}48$ kJ$/$V$.$mol
