CORROSION ENGINEERING. PLEASE ANSWER QUESTION CLEARLY WITH STEPS. I WILL LEAVE A GOOD RATING VERY VERY QUICKLY. I PROMISE!!

The active-passive system of an alloy is defined by the following electrochemical parameters: a) Please use the mixed potential theory to construct anodizing polarization curve for that active-passive alloy by calculating the critical passivation current density (25 points). Note: Critical passivation current density is calculated by substituting the anodic current density ia with Icrit and the anodic potential E with Epp in the Tafel equation
