$R - \mathop {\mathop C\limits^{||} }\limits^O - OH\xleftarrow{{{H_3}{O^ + }}}X\xrightarrow{{[H]}}RC{H_2}N{H_2};$
'$X$' is
| $M^{x+}\, (aq)\,/M(s)$ |
$A{u^{3 + }}(aq)/$ $Au(s)$ |
$A{g^ + }(aq)/$ $Ag(s)$ |
$F{e^{3 + }}(aq)/$ $F{e^{2 + }}(aq)$ |
$F{e^{2 + }}(aq)/$ $Fe(s)$ |
| $E^o\,M^{x+}$ $\,/M(V)$ | $1.40$ | $0.80$ | $0.77$ | $-0.44$ |
If $E_{Z{n^{2 + }}/Zn}^o = - 0.76\,V,$ which cathode will given a maximum value of $E_{cell}^o$ per electron transferred?
