MCQ
The enthalpy changes for the following processes are listed below :
$Cl_2(g) \to 2Cl(g), 242.3\, kJ\, mol^{-1}$
$I_2(g) \to 2I(g), 151.0\, kJ\, mol^{-1}$
$ICl(g) \to I(g) + Cl(g), 211.3 kJ\, mol^{-1}$
$I_2(s) \to I_2(g), 62.76\, kJ\, mol^{-1}$
Given that the standard states for iodine and chlorine are $I_2(s)$ and $Cl_2(g)$, the standard enthalpy of formation for $ICl(g)$ is .............. $\mathrm{kJ\,mol}^{-1}$
$Cl_2(g) \to 2Cl(g), 242.3\, kJ\, mol^{-1}$
$I_2(g) \to 2I(g), 151.0\, kJ\, mol^{-1}$
$ICl(g) \to I(g) + Cl(g), 211.3 kJ\, mol^{-1}$
$I_2(s) \to I_2(g), 62.76\, kJ\, mol^{-1}$
Given that the standard states for iodine and chlorine are $I_2(s)$ and $Cl_2(g)$, the standard enthalpy of formation for $ICl(g)$ is .............. $\mathrm{kJ\,mol}^{-1}$
