Using the information given below, estimate the enthalpychange for the reaction of carbon monoxide and chlorine to producephosgene. CO(g) + Cl2(g) -> Cl2CO(g) Bond Average Bond Dissociation Enthalpy (kJ/mol)C-Cl 339 Cl-Cl 242 C=O 745 C=O 1046 Using the information given below, estimate the enthalpychange for the reaction of carbon monoxide and chlorine to producephosgene. CO(g) + Cl2(g) -> Cl2CO(g) Bond Average Bond Dissociation Enthalpy (kJ/mol)C-Cl 339 Cl-Cl 242 C=O 745 C=O 1046 C-Cl 339 Cl-Cl 242 C=O 745 C=O 1046
Explanation / Answer
We Know that : The given equation is : CO(g) +Cl2(g) -> Cl2CO(g) Hrxn. = Bond energy of thereactants - Bond energy of the products = (1046 + 242 ) kJ - [( 745 + 2 ( 339 ) ] kJ = -135 kJ
