R = fe Re + f, Rs
R = fe (Ra – Rd) + fs (Rc – Rd)
So
R = fe Ra + fs Rc – Rd
(Note that -Rd denotes that the direction of the reaction is the
opposite of that reported in the Rittmann/McCarty tables) Also note
that if the direction of a reaction is reversed, the sign on the free
energy value also changes).
