Table 2
Apparent activation energy values for Pb and Pb-In alloys in 4 M H2SO4 solution at both peak (I) and passive region.
| Pb or alloys | (kJ·mol−1) at Peak (I) | (kJ·mol−1) (in passive region at 1.2 V) |
| Pb | 24.20 | 52.00 | Alloy (I) | 26.20 | 49.00 | Alloy (II) | 21.30 | 45.60 | Alloy (III) | 18.00 | 41.50 | Alloy (IV) | 16.60 | 26.11 | Alloy (V) | 15.00 | 22.00 |
