Question

Calculate $Δ_{f} H^{⊖} I C l (g)$ from the data
$Δ H_{d i s s o c i a t i o n} C l_{2} (g) = 57.9 K c a l m o l^{- 1}$
$Δ H_{d i s s o c i a t i o n} I_{2} (g) = 36.1 K c a l m o l^{- 1}$
$Δ H_{d i s s o c i a t i o n} I C l (g) = 50.5 K c a l m o l^{- 1}$
$Δ H_{d i s s o c i a t i o n} I_{2} (g) = 15.0 K c a l m o l^{- 1}$

Δ H = 4 K c a l m o l^{- 1}
