To calculate the anodic Tafel slope for the oxidation of Fe in a 0.1 M FeCl2 solution, we will use the Tafel equation: = b * log10 i / i0 where is the overpotential, b is the Tafel slope, i is the current density, and i0 is the exchange current density.We are given the following values:- Current density i = 0.5 mA/cm- Exchange current density i0 = 0.1 mA/cm- Temperature T = 298 K- Area A = 0.2 cmFirst, we need to calculate the overpotential . We can use the Butler-Volmer equation to do this: = RT/nF * log10 i / i0 where R is the gas constant 8.314 J/molK , T is the temperature 298 K , n is the number of electrons transferred 2 for Fe oxidation , and F is the Faraday constant 96485 C/mol . = 8.314 * 298 / 2 * 96485 * log10 0.5 / 0.1 = 0.214 VNow, we can use the Tafel equation to calculate the anodic Tafel slope b :0.214 = b * log10 0.5 / 0.1 b = 0.214 / log10 5 b = 0.214 / 0.699b 0.306 V/decadeThe anodic Tafel slope for the oxidation of Fe in a 0.1 M FeCl2 solution at a current density of 0.5 mA/cm is approximately 0.306 V/decade.
