PART II: Answer true or false the following (10 Marks) 1. The diffusion controlled reaction occurs when the rate depends on the rate the rate of charge transfer while the kinetic controlled reaction occurs when depends on the spontaneous transfer of the electroactive species. [ 1 2- The cathodic reaction rate becomes faster when the applied potential is more positive than equilibrium potential. 3- The overpotential () is the potential applied to the working electrode relative to the redox equilibrium potential. 4- The exehange current (I0) is the current at equilibrium is an intensive parameter and is not influenced by the electrode surface area and the kinetics or speed of the reaction. [ ] 5. Galvanic corrosion occurs in the area when the ion concentration gradient is existing. ] 6- In linear sweep voltammetry (LSV) the ions flux to the electrode surface is considerably smaller at high scan rates and is high at low sean rates
