where F is Faraday's constant (9.6485 ×10 4 C mol -1 ), and n is the proportionality constant for the number of moles of electrons produced for each mole of acetate oxidized (Eqn. 1). Researchers usually consider that n=8, or equivalently that the coulombic efficiency is 100%. However, recent work using genome-scale metabolic modeling of EABs from G. sulfurreducens indicates that at concentrations greater than 0.5 mM, n may be as low as 7.2. Without accounting for the specific reaction mechanism, we know that v is proportional to the rate constant k (i.e., v/p=k, where p is a constant of proportionality), and therefore, according to the Arrhenius equation, the reaction rate constant will show temperature dependence.
