The ES1U1B1cellS1U1B0 value for redox reactions involving the hydronium ion (H+) does depend on the pH, as the concentration of H+ affects the reduction potential of the half-reaction involving H+. In this case, the redox reaction involves the reaction of H+ with FeS1U1P12 and FeS1U1P13, so the pH will have an effect on the ES1U1B1cellS1U1B0 value.
