Consider an electrochemical cell with a copper metal electrode immersed in a solution of copper sulfate, and a platinum electrode in a solution of hydrogen sulfate. The current is measured at 25°C while the cell potential is varied. The following data is obtained for the anodic and cathodic currents:Anodic current:Cell potential (V): 0.20 0.30 0.40 0.50 0.60Current (mA): 1.01 1.80 3.04 4.58 6.25Cathodic current:Cell potential (V): -0.20 -0.30 -0.40 -0.50 -0.60Current (mA): -1.00 -1.79 -3.02 -4.54 -6.19Calculate the anodic and cathodic Tafel slopes for this electrochemical cell.
