$k =\left(6.5 \times 10^{12} \,s ^{-1}\right) e ^{-26000 K / T }$
is followed for the decomposition of compound $A$. The activation energy for the reaction is $.....\,kJ$ $mol ^{-1}$. [nearest integer]
(Given: $R =8.314 \,J\, K ^{-1}\, mol ^{-1}$ )
$I$. $\log \,\,K\, = \,\frac{{nF{E^o}}}{{2.303\,RT}}$
$II$. $K\, = \,{e^{\frac{{nF{E^o}}}{{RT}}}}$
$III$. $\log \,\,K\, = -\,\frac{{nF{E^o}}}{{2.303\,RT}}$
$IV$. $\log \,\,K\, = 0.4342\,\,\frac{{-nF{E^o}}}{{RT}}$
