Using data found in Appendix $E$ of your textbook calculate the nonstandard emf for each of the following reactions if the concentration of each of the ions in these reactions is $0\mathrm{.}0005$ molar and everything else is standard $($use $298K$ for the temperature, $R=8\mathrm{.}314\frac{J}{m}ol-K,$ and $F=96,485\frac{C}{m}ol)$:

$($a$)2L{i}^{+}(aq)+1Mn(s)2Li(s)+1M{n}^{2+}(aq)$

$E=$ v

$($b$)1H{g}^{2+}(aq)+2F{e}^{2+}(aq)1Hg(l)+2F{e}^{3+}(aq)E=$ v

$($c$)1S{n}^{2+}(aq)+2C{u}^{+}(aq)-1Sn(s)+2C{u}^{2+}(aq)$

$E=$

$($d$)1S{n}^{4+}(aq)+1Co(s)-1S{n}^{2+}(aq)+1C{o}^{2+}(aq)$

$E=$
