5. A chlor-alkali cell is used in industry to produce Cl2, H2, and NaOH. The cell is divided into two sides of anodic and cathodic one. The anodic reaction is the oxidation of cl ion, which take place under slightly acidic conditions at a pH of 4. The cathodic reaction is the evolution of Hz under basic conditions of a pH of around 14. The salt solution on the anodic side is 5M NaCl. 1) Write the half-cell reactions with the standard reduction potentials (You may need to search literature for this). What is the standard cell potential at 25C? 2) Kinetic data are provided for the Clz evolution in 5M NaCl at 20C (from literature). Calculate the Tafel slope, exchange current density, and the transfer coefficient for the reaction. 60,300 22,300 8.080 4,110 1,230 621 240 116 30.1 Current density (A/m2) Overpotential (V) 0.2091 0.1703 0.1359 0.1036 0.05512 0.04047 0.02547 0.01658 0.00489
