Five iron rivets, 3.2 cm? of total exposed area each, are inserted in a copper sheet of 7430 cm? exposed area. The sheet is immersed in an aerated, stirred, conducting solution in which the uncoupled iron corrodes at 0.165 mm per year. a. Calculate the corrosion rate of the rivets in mm/year b. What is the corrosion rate (mm/year) of an iron sheet in which five copper rivets are placed with the same dimensions?

Question
Five iron rivets, 3.2 cm2 of total exposed area each, are inserted in a copper sheet of 7430 cm? exposed area. The sheet is immersed in an aerated, stirred, conducting solution in which the uncoupled iron corrodes at 0.165 mm per year. a. Calculate the corrosion rate of the rivets in mm/year b. What is the corrosion rate (mm/year) of an iron sheet in which five copper rivets are placed with the same dimensions? EMF Table: Fe | Fe2+ Fe Fe2+ + 2e +0.441 Cu Cu?+ Cu Cu2+ + 2e- -0.337
