A student is studying the electrochemical reaction of the metal copper in acidic solution. They measure the current density at different applied potentials and obtain the following data:Potential vs. SHE (V) | Current Density (mA/cm²)---|---0.0 | 0.00.1 | 0.50.2 | 2.00.3 | 5.00.4 | 11.0Using this data, calculate the anodic and cathodic Tafel slopes, and determine the rate constant for the electrochemical reaction.
