$($a$)$ Compute the voltage at $25C$ of an electrochemical cell consisting of pure cadmium immersed in a $1{10}^{-3}M$ solution of $C{d}^{2+}$ ions and pure iron in a $0\mathrm{.}6$ M solution of $F{e}^{2+}$ ions.

$V=$

$($b$)$ Determine the spontaneous electrochemical reaction for iron $($reduced$/$oxidized$)$ and cadmium $($reduced$/$oxidized$).$

Iron is $q,$

Cadmium is
