3. (30) A galvanic cell is composed of a silver half-cell and a and an iron half-cell. a) (15) If the silver half-cell is at 20C and the [Ag] is 2x10 mol/1 and the iron half-cell is at 35C and [Fe]2+ is 0.4 mol/1. What is the open cell potential? b) (15) If this cell is closed, it will behave just like a corrosion reaction. Which electrode corrodes and at what rate? Neglect concentration polarization. For Agi=10-10 A/cm, B=0.13 For Fei. 10 A/cm, B=0.10 Constants are for the In version of the equation. 3.
