To calculate the activation energy for the electrochemical reaction of zinc metal being oxidized to form Zn2+ ions in a solution containing HCl, we need to analyze the Tafel plot. The Tafel plot is a graphical representation of the relationship between the electrode potential E and the logarithm of the current density log j for an electrochemical reaction.The Tafel equation is given by:E = E0 + 2.303 * RT / nF * log jWhere:E is the electrode potentialE0 is the standard electrode potentialR is the gas constant 8.314 J/molK T is the temperature in Kelvin 25C = 298.15 K n is the number of electrons transferred in the reaction for Zn to Zn2+, n = 2 F is the Faraday constant 96485 C/mol The activation energy Ea can be determined from the Tafel plot by finding the slope of the linear region of the plot. The slope of the Tafel plot is given by:Slope = 2.303 * RT / nF * Where is the charge transfer coefficient, which is typically between 0.5 and 1 for most electrochemical reactions.To calculate the activation energy, we need the experimental data from the Tafel plot. Since the data is not provided, we cannot calculate the exact activation energy for this specific reaction. However, if you have the slope of the Tafel plot from the experimental data, you can use the above equations to determine the activation energy.
