Homework; Estimate the corrosion rate, penetration rate, and $E_{\text{c}\text{o}\text{r}\text{r}}$ for steel tank containing aerated acid $)=(2.$ Assume both anodic and cathodic reactions are under activation control. $[F{e}^{+2}]=0\mathrm{.}1M$ at $298K.$

$i_{0,Fe}=1{10}^{-6}\frac{A}{c}{m}^2,{}_a=0\mathrm{.}1\frac{V}{d}$ecade

$i_{O,H}=1{10}^{-5}\frac{A}{c}{m}^2,{}_c=-0\mathrm{.}1\frac{V}{d}$ecade

Homework; Estimate $i_L$ at $298K$ for copper reduction reaction with bulk concentration of $[C{u}^{+2}]=0\mathrm{.}1M$ in unstirred solution where $=0\mathrm{.}3mm.D_{Cu+2}=7{10}^{-10}\frac{m^2}{s}$

$i_c=i_L=nF{D}_0\frac{C_O^{\text{b}\text{u}\text{l}\text{k}}}{},i_L=nF{D}_{\text{i}\text{o}\text{n}}\frac{C_0^{\text{B}\text{u}\text{l}\text{k}}}{}=2^{**{96500}^{**}}7{10}^{-10}\frac{0\mathrm{.}1}{0\mathrm{.}0003}=4\mathrm{.}58m\frac{A}{c}m2$
