\(\therefore \,\,\,\log \,\,K = \,\,\frac{{nF{E^o}_{cell}}}{{2.303\,\,\,RT}}\,\)
\(\therefore \,\,\,\log \,\,K = \frac{{2 \times 96500 \times 0.46}}{{2.303 \times 8.314 \times 298}}\,\,\,\,\,\left[ {\,R\, = \,8.314\,\,joule\,} \right]\)
\(\therefore \,\log \,K\,= \,15.559\,\,\,\,\,\therefore \,\,K\,\, = \,\,Anti\log \,\,15.559\,\,\,\)
\( = \,\,3.625\, \times \,{10^{15}}\,\, \approx \,\,4\, \times \,{10^{15}}\)
$E^o_{Cr_2O_7^{2-}/Cr^3+} =1.33\,V:$ $E^o_{Cl/Cl^-} =1.36\,V$
ઉપર આપેલા માહિતીને આધારે નીચેનામાંથી ક્યો પ્રબળ ઓક્સિડેશનકર્તા છે ?
$E^oFe^{3+}_{(aq)} + e^{-} \rightarrow Fe^{2+}_{(aq)}$ કેટલા ............ $\mathrm{V}$ થાય?
$Fe^{3+}\,\,_{(aq)} + 3e^{-} \rightarrow Fe_{(s)}$ ; $E^o = -0.036 \,volt; $
$Fe^{2+}_{(aq)} + 2e^{-} \rightarrow Fe_{(s)}$ ; $E^o = -0.440 \,volt$
