The rate constants of the above reaction at $200 \,K$ and $300 \,K$ are $0.03 \,min ^{-1}$ and $0.05 \,min ^{-1}$ respectively. The activation energy for the reaction is $....J$ (Nearest integer)
(Given : In $10=2.3$
$R =8.3\,J\,K ^{-1}\, mol ^{-1}$
$\log 5=0.70$
$\log 3=0.48$
$\log 2=0.30$

${\text{Propanoic acid }}\xrightarrow{{SOC{l_2}}}X\xrightarrow{{N{H_3}}}Y\xrightarrow{{B{r_2} + KOH}}Z$
What is the compound $Z$
$F{e^{3 + }}(aq) + {e^ - } \to F{e^{ - 1}}(aq);\,{E^o} = + 0.77\,V$
$A{l^{3 + }}(aq) + 3{e^ - } \to Al(s);\,{E^o} = - 1.66\,V$
$B{r_2}(aq) + 2{e^ - } \to 2B{r^ - }(aq);\,{E^o} = + 1.08\,V$
Based on the data given above, reducing power of $F{e^{2 + }},\,Al$ and $B{r^ - }$ will increase in the order
