${N_2}{O_4}(g)\, \to \,2N{O_2}(g)$
Data for the given reaction is
$\Delta H = +54\,kJ$ and $E_a = + 57.2\,kJ$
.......$kJ$
$H _{2( g )}+ Br _{2( g )} \rightarrow 2 HBr _{( g )}$
Given that bond energy of $H _{2}$ and $Br _{2}$ is $435 \;kJ mol ^{-1}$ and $192 \;kJ mol^{-1}$, respectively, what is the bond energy (in $kJ mol ^{-1}$ ) of $HBr?$
