GALVANIC CELLS: THE NERNST EQUATION

Prelab

$C{l}^{-1}+Mn{O}_4^{-1}M{n}^{+2}+C{l}_2$

Balance the equation using the ion$-$electron $($half$-$cell$)$ method. Assume acidic

solution.

Calculate the $E_{\text{c}\text{e}\text{l}\text{l}}^o.$

Calculate $E_{\text{c}\text{e}\text{l}\text{l}}$ when $M{n}^{+2}$ and $C{l}^{-1}$ are each $1\mathrm{.}0M,Mn{O}_4^{-1}$ is $1\mathrm{.}0{10}^{-4}M,C{l}_2$ is at $1$

atm pressure, and the $pH$ is $3\mathrm{.}00.$

Calculate the equilibrium constant, $K_{eq},$ for the reaction.
