Q. If enthalpy of atomisation for $Br_{2(I)}$ is $x \,kJ/mol$ and bond enthalpy for $Br_2$ is $y\, kj/mol$, the relation between them :

JEE MainJEE Main 2020Thermodynamics

Solution:

Enthalpy of atomisation of $Br_{2}\left(l\right)$
$\Delta H_{atoms}=\Delta H_{vap}+\Delta H_{BE}$
$x=\Delta H_{vap}+y$
$so,\, x>\, y$
