A certain half$-$reaction has a standard reduction potential $E_{\text{r}\text{e}\text{d}}^0=-0\mathrm{.}30V.$ An engineer proposes using this half$-$reaction at the cathode of a galvanic cell that must provide at least $1\mathrm{.}00V$ of electrical power. The cell will operate under standard conditions.

Note for advanced students: assume the engineer requires this half$-$reaction to happen at the cathode of the cell.

Also write the half reaction as it would occur at the anode
