you are considering using a new experimental metal, impossibrium $($Im$),$ for a valve in a corrosive environment. Tests indicate hydrogen reduction will be the cathodic reaction. Create the potential plot $($including labeling corrosion potential and corrosion current density$)$ and determine the corrosion current density given the following information:

io$,$ Im $=7*10-8$ A$/$cm$2$

io$,$H$2=5\mathrm{.}5*10-8$ A$/$cm$2$

$$Im$=0\mathrm{.}175$ V

$$H$2=+0\mathrm{.}0$ V

Assume all Tafel slopes are $\backslash$pm $0\mathrm{.}10$ V$/$decade
