Cоnversiоn оf molecules with C=C double bonds cаn be converted into molecules with а single C-C bond by аddition of (reaction with) chlorine gas, Cl2(g). The balanced equation is shown below for reaction of ethylene with chlorine gas to make dichloroethane. Using the bond dissociation energy information provided in the equation, what is the enthalpy of this reaction as written, ΔHr, in kJ/mol?
