Using the table of standard molar enthalpies of formation, (AH)298 , determine the standard reaction enthalpy, (AHA)298 for the reaction of hydrogen chloride with ethylene (ethene) to form chloroethane: C2H4 (g) + HCl (g) → C2H5Cl (g) ө. (AH)298 kJ/ mol HCI (g) - 92.3 - + 52.3 C2H4 (g) C2H5Cl (g) - 111.7 -
