Figure 4

Correlation between the current activation energy Ea (kJ/mol) from polarization and impedance measurements1 and the current entropic factor of Arrhenius—R·ln(Act/Ω cm2)/(J K−1 mol−1) for the three acids at atmospheric pressure and separately. (●): HCl, (○): H2SO4, (▲): H3PO4, Solid line: fit in linear regression for both acids.
