For the corrosion of zinc in an acid solution, the standard$-$state current

density for the zinc half$-$cell is $10-3$ A$/$cm$2,$ and the slope of the

electrochemical potential plot $($i vs V$)$ is $+0\mathrm{.}09$V$.$ Calculate the

electrochemical potential of this half$-$cell at a current density of $1$ A$/$m$2.$

Note: see the table for value of zinc half$-$cell standard$-$state potential.
