A certain half$-$reaction has a standard reduction potential $E_{\text{r}\text{e}\text{d}}^0=+0\mathrm{.}85V.$ An engineer proposes using this half$-$reaction at

the anode 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 anode of the cell.
