1. (18 pts) A metallic zinc plate of 2 cm x 3 cm is corroding at 25C in 100 ml of 0.1 M of H* with an initial concentration of Zn+ of 1x10M. a. Calculate the corrosion potential and initial corrosion speed. b. Consider that the reaction runs a constant speed for 1h, calculate new species concentration. What would be the new reaction rate after 1h? Is it significantly different?. For Zinc i, 102 A/cm, p=0.07 For H i 10 A/cm, B=0.05 In form of the equation
